Abstract:
Volatile organic contaminants are a problem in spacecraft, evaluators, and other closed cabin atmospheres and must constantly be measured. Consequently, a chemical high vacuum system for the desorption and manipulation of desorbates from solid adsorbents was developed. Essentially, the system is provided with three provisions for trapping the contaminant depending on its volatility. The high boilers are trapped in the first section, the compounds with low vapor pressure are collected in the middle section, and the noncondensables in the third section of the apparatus.
