The following specification particularly describes the invention and the manner in which it is to be performed : -

FLAME PHOTOMETER
Flame photometer for detecting accurately and simultaneously all the four alkyl metal such as Na, K, Ca, & Li present in the sample which is displayed on the graphic LCD thereby providing concentration of the elements present in the sample.
Conventional flame photometer detect only one individual element at a time which is time consuming and a large amount of sample is required for testing all the four elements.
Further the quantity of sample taken each time may vary and thereby giving a enormous result.
The principle object of this invention is therefore to provide a flame photometer which can detect all the four element (Na, K, Ca, & Li) simultaneously from a single sample.
Further object of this invention is to provide a detector block cylindrical in nature having four perforation for four optical path focusing at a single point towards the flame provided with four filters & sensors in the path for respective element (Na, K,
Ca, & Li).
Flame photometry is based on the fact that compounds of alkali and alkaline earth metals can be thermally excited in a low temperature flame and when the atoms return to the ground state they emit radiation, which lies mainly in the visible region of the spectrum. Each element emits radiation at a wavelength specific to that element.
Over a certain range of concentration the intensity of the emitted radiation is directly proportional to the number of atoms returning to the ground state. This in turn
Proportional to the absolute quantity of species volatilized in the flame i.e. light emitted is proportional to the sample concentration. An optical filter and a photo
2

detector, which provides a signal proportional to the sample concentration, measures the intensity of that light, isolate the light emitted at its characteristic
wavelength.
Such an electrical signal is processed with the help of V to F Converter and the micro controller. This instrument can measure four elements viz. Na, K, Ca, Li, simultaneously and their concentrations are displayed in ppm or mEq or % on Graphic LCD (240X128)
