Microprocessor Flame Photometer, Model-1382 is an ideal instrument for the determination of sodium, Potassium, Calcium and Lithium. It uses the latest Microcontroller technology and advanced engineering techniques so as to give enhanced and reproducibility. It has soft touch membrane key for ease of operations. the solution is aspirated through an automiser, Air sample and the fuel are mixed in the mixing chamber which is then sprayed as a very fine mist into the flame. The color of the flame is changed depending upon the concentration of elements present. Radiations from the flame passes through the sensing system and specific narrow band interference filter which permits only the characteristic radiation to pass to the photo-detector. The output of the photo-detector is then processed by the microcontroller and the final results are displayed on the digital display. The System has 5-Point calibration facility and no linearity correction is provided through an automatic curve fitting software. Facility has been provided for re-standardization with a single standard, thereby, eliminating the need of the multiple standards once a calibration has been performed.
