SPECTRUM ANALYZER Russian patent published in 1995 - IPC

FIELD: analysis of materials. SUBSTANCE: spectrum ANALYZER has microphotometer, mechanism for movement of holder of photoplate, storage of spectrum of standards, control unit amplifier, analog-to-digital converter, storage of spectrum of sample, concentration computing unit and register. ANALYZER is supplemented with counter, unit setting reference voltages, comparator, speed regulator, linear movement transducer, pulse former and former of sampling pulses. Changes of frequency of sampling and speed of movement of holder of photoplate are achieved depending on intensity of spectral line: growth of its intensity results in increase of frequency of sampling of signal from output of microphotometer and in decrease of speed of movement of holder of photoplate. EFFECT: improved efficiency of analysis. 2 cl, 2 dwg
