METHOD AND ANALYZER FOR IMPLEMENTING METHOD OF DETERMINING CONTENT OF NITROGEN OXIDES IN ROCKET OXIDIZER Russian patent published in 2019 - IPC G01N33/22 G01N21/00 G01N21/17 

FIELD: measuring equipment.

SUBSTANCE: group of inventions relates to determination of nitrogen oxides in rocket oxidants and can be used in laboratories for quality control of rocket fuel. Method for determining content of nitrogen oxides in rocket oxidizer involves cooling a charge of an oxidant, continuously measuring the power of the light flux passing through the vapor layer above the oxidant surface, fixation of sample temperature when maximum power of light flux is achieved and calculation of mass fraction of nitrogen oxides. Analyzer for implementing said method is a housing, inside which there are a tray with a cover and a temperature sensor, two thermoelectric modules, thermal accumulator, light emitter, photodetector, amplifier circuit, millivoltmeter, electronic thermometer, thermostat, thermal insulation, radiator, fan and power supply unit.

EFFECT: simplification and acceleration of determination.
