DEVICE FOR SPECTRAL ANALYSIS Russian patent published in 1994 - IPC

FIELD: analysis of materials. SUBSTANCE: device has microphotometer, mechanism for photo plate movement, memory unit for spectrum standards, control unit, amplifier, photodetector, analog-to-digital converter, memory unit of sample spectrum, concentration computation unit and recorder. TV indicator, first and second digital-to-analog converters are introduced to accomplish the goal of invention. In addition device has multiplexer, reading address generator, pulse oscillator, switch, linear movement detector, pulse shaper, counter, memory unit of wavelengths and indicator. Curves which are proportional to intensity of analytical lines of sample and standard are shown at screen of cathode-ray tube of TV indicator. Operator checks positions of maximums of these lines and when they do not match he compensate errors. EFFECT: increased functional capabilities. 2 cl, 4 dwg
