Gas Analyzer for Operation Monitoring of Contaminants Concentrations in Atmosphere 2000-01-2346

ABSTRACT

In April 1998 during the 24th prime crew operation the first mock-up of the habitation atmosphere harmful contaminants analyzer was delivered to the MIR Space Station.

Concentrations of various compounds including ammonia, freon, aromatic hydrocarbons, nitrogen oxides, carbon monoxide, methane and a number of other harmful contaminants were constantly measured by the device for half a year.

The device mock-up test results allowed to make a number of important conclusions underlying the development of the operational monitoring gas analyzer designed for nominal and off-nominal toxicological monitoring of the ISS Service Module (SM) air.

The results of measurements made by the device mock-up are presented in the article. The analysis of positive and negative aspects revealed in operation of the device mock-up aboard the MIR Space Station is given, the principle of operation of the gas analyzer intended for the ISS SM is reviewed, technical characteristics are presented in the article.
