TITLE OF THE INVENTION METHOD AND SYSTEM FOR CHEMICAL AND PHYSICAL CHARACTERIZATION OF COMPLEX SAMPLES BACKGROUND OF THE INVENTION [0001] This application claims the benefit of U.S. Provisional Patent Application No. 60/817,076. filed on June 29, 2006. This application is also related to U.S. Patent Application No. 11/582,558, filed October 18, 2006, entitled METHODS AND SYSTEMS FOR CHEMICAL AND PHYSICAL CHARACTERIZATION OF COMPLEX SAMPLES. The entire content of these related applications is incorporated herein by reference. Field of the Invention [0002] The present invention relates to a method and system for rapid determination of composition, of crude oils and fractions thereof, as well as other substances and obtaining the information necessary to assess the yield of commercially valuable fuel and lube oil fractions, for example, in a single process. In particular, the present invention is directed to a method and system for determining yields and compositions in terms of a simultaneous boiling point distributions and hydrocarbon types breakdown, across the boiling range of interest, and determining the changes in chemical composition and yields in upgrading and/or conversion processes, compiling a preliminary evaluation of a variety of geochemical parameters or biomarkers for the correlation to fingerprint identification, maturity, origins, etc., and compiling experimental data to chemical and physical properties. Background of the Technology [0003] Gas Chromatography is a chemical analysis instrument for separating chemicals in a complex sample. A gas chromatograph uses a narrow tube, known as a column, through which different chemical constituents of a sample pass in a gas stream. The gas stream is also called the carrier gas or mobile phase. Gas Liquid Chromatography (GLC), or simply Gas Chromatography (GC) is a type of chromatography in which the mobile phase is a gas. The chemical constituents within the sample pass through the column at different rates, depending on their various chemical and physical properties and their interaction with a specific column phase . This column phase is called the stationary phase and is a microscopic layer of liquid on an inert solid support in the column. If the phase is bonded directly to the tubing it is called a capillary column The column is often flexible so that a very long column can be wound into a small coil. [0004] The column(s) in a GC are contained in an oven, the temperature of which is precisely controlled (e.g., electronically). The rate at which a sample passes through the column is directly proportional to the temperature of the column. The higher the column temperature, the faster the sample moves through the column. However, when a sample moves quickly through the column, it interacts less with the stationary phase, and the analytes are less separated. [0005] As the chemical constituents exit the end of the column, they are detected and identified electronically by a detector. The stationary phase separates the different components, causing each one to exit the column at a different time, which is called the retention time. Other parameters can also be used to alter the order or time of the retention, such as the carrier gas flow rate and the temperature as well as the chemical nature of the phase.. [0006] However, conventional GC may require high resolution techniques in order to provide a satisfactory analysis of the chemical constituents of a complex sample. SUMMARY OF THE INVENTION [0007] There is a need in the art, therefore, for methods and systems for analyzing complex samples using gas chromatography that do not require high resolution techniques. The present invention solves the above-identified needs, as well as others by providing methods and systems for rapid determination of composition of crude oils and fractions thereof, as well as other substances, and in a single process obtaining the information necessary to assess the yield of commercially valuable petroleum fuel and lube oil fractions using Gas Chromatography - FID/Mass Spectrometry. Variations of the present invention also include auto sampler features, a wall coated capillary column, a temperature programmable injector and data processing features for compiling and processing experimental data. Embodiments of the present invention further include a computer system with application software and a communication network. The present invention, in one embodiment, provides a graphical user interface for the entry of data, and for displaying information, such as in a graphical manner, to show the relationship of various determined outputs and results. [0008] Among other things, the present invention enables multidimensionality with simple hardware, wherein a low resolution column is sufficient for analyses and additional highly resolving techniques are not required. In addition, the present invention provides hydrocarbon type analysis and Simulated Distillation ("SimDis") data, including providing such analysis and data in a single process. [0009] Additional advantages and novel features of the invention will be set forth in part in the description that follows, and in part will become more apparent to those skilled in the art upon examination of the following or upon learning by practice of the invention.

[00036] Figures 25-51 contain various data and other information produced using systems and methods of the present invention. DETAILED DESCRIPTION [00037] Referring now to Figure 1, therein shown is the general architecture of an exemplary Gas Chromatography — FID/Mass Spectrometry apparatus (GC- FID/MS), as used in accordance with a method and system of the present invention. [00038] The GC-FID/MS of Figure 1 includes a gas chromatograph (100), which includes an injector (200), a column (300), and an oven (400); a mass spectrometer (MS) (600); a flame ion detector (FID) (500); a divider (700); and a data processing system for acquiring and processing the data. One variation provides a graphical user interface for the entry of data and for displaying information, such as in a graphical manner, to show the relationship of various determined outputs and results. [00039] In certain embodiments, the GC-FID/MS may also include an automatic liquid sampler (ALS). In addition, the column may be a wall coated capillary column, and the inlet may be a temperature programmable injector. [00040] In operation, the gas chromatograph (100) utilizes the difference in chemical properties between different chemical constituents in a sample to separate the chemical constituents. As the different chemical constituents exit the gas chromatograph at different times, the mass spectrometer, which is located downstream in the gas flow, evaluates the chemical constituents separately and is able to identify the constituents. [00041] The mass spectrometer (600) identifies the various chemical constituents that pass through it at a flow D2 by breaking each constituent into ionized fragments and detecting these fragments using the mass to charge ratio of the fragments. [00042] The FID (500) is, for example, an ion detector that uses an air- hydrogen flame to produce ions. As the chemical constituents in the sample exit the gas chromatograph at a flow D1, they pass through the flame and are burned, producing ions. The ions then produce an electric current, which is used to provide the signal output of the FID. The FID of some embodiments can only detect components that can be burned, and the FID destroys the components during detection. Thus, no further detection is made after the FID completes processing. [00043] However, it should be noted that the nature and amount of constituents that flow through the mass spectrometer 600 and through the FID 500 may be similar in order to combine the results obtained by the MS 600 and by the FID 500. For this reason, the apparatus of this embodiment of the present invention also includes a divider (700) that divides the exiting chemical constituent between the FID and the MS, so that portions of the exiting chemical constituent are analyzable by both the FID and MS simultaneously. The divider 700 should be able to prevent molecule discrimination in the constituents and distribute the constituents equally between the flow D1 and the flow D2, which is achieved by heating the constituents at a temperature necessary to ensure that no molecular discrimination occurs. Furthermore, pneumatic control module (PCM) may be part of the GC-FID/MS, that controls the pressure of the sample as it passes through the divider in order to preserve an equal ratio of constituents flowing through D1, and another PCM that controls the pressure of the sample as it passes through the divider in order to preserve an equal ratioof constituents flowing through D2, so that the amount of constituents that pass through D1 is about equal to the amount of constituents that pass through D2. In one embodiment, the divider may be or include a micro influx divider. In one embodiment, the division between the portion of the exiting chemical constituent that is sent to the MS (D2) and the portion of the exiting chemical constituent that is sent to the FID (D1) are approximately equal, so that approximately D2/D1 = 1. The influx of chemical constituents are precisely divided in a controlled manner without compromising the sample integrity. The controlled division of the elution of the column towards the two detectors is prevented from being discriminatory, either of light components or of heavy components, for the samples under analysis. [00044] An exemplary embodiment, of the present invention uses a megabore capillary high throughput column and a temperature programmable injector. In one embodiment, the column includes a capillary column element that is about 5 m by 0.53 mm i.d. by about 0.1 µm; the FID detector is an FID 440 Celsius; the carrier gas is Helium at a constant flux rate of about 12 mL/min; the oven is programmed to start at about 40° Celsius, to raise about 10° Celsius/min until about 430° Celsius is reached, to maintain the temperature for about 12 minutes, with an equilibrium time of about two minutes; the injection volume is about 0.2 µL; and the dilution is about 2% in CS2. It should be noted that hydrogen could be used instead of helium as the carrier gas. [00045] In one embodiment of the present invention, the GC-FID/MS may be used to analyze the physical and chemical characterization of petroleum fractions. Using the GC-FID/MS, a rapid determination may be made of the composition of crude oils, for example. This apparatus and method may also be applied to fractions of crude oil, or other substance. Information necessary to access the yield of commercially available valuable fuel and lube oil fractions can also be obtained in a single process. Using quantitative software or other processing, the mass spectral data may be converted to weight and volume percent chemical composition. The system and method provide the boiling point distribution and chemical composition of the analyzed substance based on saturate and aromatic group types. [00046] Crude oil, for example, may contain a mixture of chemical compounds from a family of several hundred chemical compounds. Some chemicals that may be found in crude oil include hexane, jet fuels fraction, diesel fractions, benzene, toluene, xylenes, naphthalene, and fluorine, in addition to other petroleum products such as heavy diesel, atmospheric residues, vacuum residues and gasoline naphtha to be used in gasolines.. The characterization of complex fractions and versatility are improved by combining the signals of the FID detector and the mass spectrometer detector in a single processing apparatus. In an exemplary embodiment, the signal from the FID detector is in the simulated distillation mode and the MD detector is in a single environment of synergistic mode. The MD detector provides ion fragmentation at continuous time intervals during the elution of the sample though the column [00047] The present invention thus is able to provide a powerful analytical tool allowing the simultaneous physical and chemical characterization of whole crude oil samples and their fractions, without the need to perform the physical separation of the hydrocarbon fractions. [00048] In an exemplary embodiment, the FID detector is in a simulated distillation mode. Simulated distillation (SimDis) is a gas chromatography technique that separates individual hydrocarbon components in their order of boiling points and is used to simulate the time-consuming laboratory-scale physical distillation procedure referred to as true boiling point distillation. Using a gas chromatograph equipped with an oven and inlet that can be temperature programmed, an FID is used for detection and measurement of the hydrocarbon analytes. The result of SimDis analysis provides a distillation curve which is a quantitative percent mass yield as a function of boiling point of the hydrocarbon components of the sample. [00049] In some embodiments, the present invention conforms with the ASTM (American Society for Testing and Materials) standards for stimulated distillation: D-2887, D-6352, and D-7169. Simulated distillation is a proven and accepted technique for the physiochemical characterization of crude and fractions of oil. Recently, ASTM D2 accepted a new method for the analysis of fractions with a final boiling point of 615 Celsius (C5 to C60). See ASTM D 7213-05. [00050] The quantitative methods of mass spectrometry can also serve as helpful tools in the chemical characterization of products with a vast range of boiling points. Mass spectrometry reports a composition in the basis of five principal groups: paraffin, napthalene, aromatic, sulfur, and non-identified. All of the ASTM methods, with the exception of those applying to napthalenes, require a chromatographic separation of the saturated and aromatics. Such separation requires high resolution methods. High resolution requires complex and costly equipment. New multidimensional analytical mechanisms, such as GC x GC and GC-MS-TOF, also require complex instruments and procedures, even for the gasoline range. [00051] The present invention enables spectrometric analysis within fractions at a low resolution. Thus, it allows simple and quick analysis. [00052] Figure 2 illustrates a block diagram of various computer system components useable with an exemplary implementation of a physical and chemical characterization of petroleum fractions by GC/SIMDIS/MS, in accordance with embodiments of the present invention. [00053] As shown in Figure 2, the controller of the present invention may be implemented using hardware, software or a combination thereof and may be implemented in one or more computer systems or other processing systems. In one embodiment, the invention is directed toward one or more computer systems capable of carrying out the functionality described herein. [00054] Figure 2 shows a computer system 1 that includes one or more processors, such as processor 4.

Various software embodiments are described in terms of this exemplary computer system. After reading this description, it will become apparent to a person skilled in the relevant art(s) how to implement the invention using other computer systems and/or architectures.

Examples of such may include a program cartridge and cartridge interface (such as that found in video game devices), a removable memory chip (such as an erasable programmable read only memory (EPROM), or programmable read only memory (PROM)) and associated socket, and other removable storage units 22 and interfaces 20, which allow software and data to be transferred from the removable storage unit 22 to computer system 1. [00057] Computer system 1 may also include a communications interface 24. Communications interface 24 allows software and data to be transferred between computer system 1 and external devices.

These signals 28 are provided to communications interface 24 via a communications path (e.g., channel) 26. This path 26 carries signals 28 and may be implemented using wire or cable, fiber optics, a telephone line, a cellular link, a radio frequency (RF) link and/or other communications channels. In this document, the terms "computer program medium" and "computer usable medium" are used to refer generally to media such as a removable storage drive 14, a hard disk installed in hard disk drive 12, and signals 28. These computer program products provide software to the computer system 1. The invention is directed to such computer program products. [00058] Computer programs (also referred to as computer control logic) are stored in main memory 8 and/or secondary memory 10. Computer programs may also be received via communications interface 24. Such computer programs, when executed, enable the computer system 1 to perform the features of the present invention, as discussed herein. In particular, the computer programs, when executed, enable the processor 4 to perform the features of the present invention. Accordingly, such computer programs represent controllers of the computer system 1. [00059] In an embodiment where the invention is implemented using software, the software may be stored in a computer program product and loaded into computer system 1 using removable storage drive 14, hard drive 12, or communications interface 24. The control logic (software), when executed by the processor 4, causes the processor 4 to perform the functions of the invention as described herein. In another embodiment, the invention is implemented primarily in hardware using, for example, hardware components, such as application specific integrated circuits (ASICs). Implementation of the hardware state machine so as to perform the functions described herein will be apparent to persons skilled in the relevant art(s). [00060] In yet another embodiment, the invention is implemented using a combination of both hardware and software. [00061] Figure 3 shows a communication system 30 of the present invention for use with the computer system 1 of Figure 2. The communication system 30 includes an accessor 31 (also referred to interchangeably herein as a "user") and a terminal 32. In one embodiment, data for use in the computer system 1 is, for example, input and/or accessed by the accessor 31 via the terminal 32, such as a personal computer (PC), minicomputer, mainframe computer, microcomputer, telephonic device, or wireless device, such as a hand-held wireless device coupled to a server 33, such as a PC, minicomputer, mainframe computer, microcomputer, or other device having a processor and a repository for data and/or connection to a processor and/or repository for data, via, for example, a network 34, such as the Internet or an intranet, and couplings 35, 36. The couplings 35, 36 include, for example, wired, wireless, or fiberoptic links. In another embodiment, the method and system of the present invention operate in a stand-alone environment, such as on a single terminal. [00062] Figure 3B shows a flow chart according to a method in accordance with an embodiment of the present invention. In step S1, a sample to be analyzed is injected into a column of a gas chromatograph along with a flowing gas via an injector. In step S2, the constituents of the sample are separated within the column of the gas chromatograph. In step S3, the constituents are moved through and out of the column with the flowing gas. In step S4, the constituents of the sample are divided as the constituents exit the column. The divided constituents are supplied to a flame ion detector and a mass spectrometer. According to various exemplary embodiments, the sample is divided via a divider, and the constituents are heated at a temperature necessary to ensure that there is no molecule discrimination between the supply of constituents to the mass spectrometer and the supply of constituents to the flame ion detector. Thus, the portion of the constituents that is sent to the mass spectrometer and the portion of the constituents that is sent to the flame ion detector are approximately equal, and the integrity of the constituents is preserved. In step S5, the characteristics of the constituents of the sample are detected via the flame ion detector. In step S6, the characteristics of the constituents of the sample are detected via the mass spectrometer. It should be noted that although steps S5 and S6 describe the detection via the mass spectrometer occurring before the detection via the flame ion detector, the order could be reversed, or the detection via both the mass spectrometer and the flame ion detector can take place at the same time. After the characteristics are detected, the data may be acquired and processed by a data processing system. The accumulated data from both detectors obtained from continuous equal time slice analysis is stored for subsequent processing. [00063] Yields and compositions, in terms of the boiling point distributions and hydrocarbon type breakdowns across the boiling range of interest, may be determined. In addition, changes in chemical compositions and yields in upgrading and/or conversion processes may be analyzed and studied. [00064] Among other things, the present invention may be used to establish a preliminary evaluation of a variety of geochemical parameters or biomarkers for the correlation to fingerprint identification, maturity, origins, etc., of crude oil or fraction thereof that is analyzed. Experimental data may be correlated to chemical and physical properties. This enables refining strategies to be planned to maximize yields of required products without affecting their quality. Feedstocks can be rapidly tested by correlating the composition of products to quality. [00065] In addition, the distribution and type of sulphur compounds in distillates may be determined. The profile and quantities of heterocompounds in distillates may be studied by coupling specific detectors to the apparatus. [00066] Exemplary results produced using application of the present invention to crude oil is shown in Figure 4. Figure 4 shows the multidimensionality of the information that may be gathered. Figure 4 also shows the results detected by the MS, the results detected by the FID, and the combined information. [00067] The present invention is fast, with high repeatability, as shown in Figures 5 and 6. Figure 5 shows the results for 3 injections, with one axis showing the signal intensity and the other showing time. The three results nearly overlap each other. The actual values for the three injections are shown in the boiling point table. Figure 6 shows another set of results for three injections of paraffinic crude oil, produced using a method and system in accordance with an embodiment of the present invention. Thus, the present invention can serve as an excellent screening technique to study the efficiency of physical distillations and refining processes and can rapidly establish the main compositional characteristics of crude oils, so that their quality for decision making purposes can be quickly established. Further, the present invention can serve as part of a quick exploration tool to establish the principle characteristics of crude oil quality allowing for decisions on refinement planning and commercialization. [00068] Figure 7 shows a retention time standard for ASTM D 7169-2005. Figure 8 shows a crude oil boiling point calibration curve. Figure 9 shows the measured results of a reference material. Figure 10 shows the measured results for a crude oil sample. Figure 11 shows algorithms used for analyzing for each time slice the contributions of each ion characteristic of the hydrocarbon group of aromatics and saturates. Although Figure 11 references algorithms disclosed in Robinson (Analytical Chemistry, Vo. 43, 11, 1971), these algorithms are exemplary only and other, more refined algorithms and multiple variant equations may be used to extract the various compositions of the various constituents of the sample being tested. These algorithms allow the superimposition of masses at various time intervals to extract the composition of each constituent.
