Abstract: GC/MS Analysis and Evaluation of Gassing Products from Crew Cabin Nonmetallic MaterialsYu Bingliang;Wei Yongjia(Institute of Space Medico-Engineering,Beijing 100094,China)Abstract:The thermal off-gassing products from twenty one types of national polymel materials were monitored using GC/MS technique as well as headspace/concentration sampling technique. The sixty nine chemcial componets were identified in all. The sources of the outgas products and toxicological characteristics of the materials were discussed.Hygienic property of the materials were evaluated and the proposition for making rational use of the materials was advanced.These will provide important basis to evaluate and select polymer materials.Keywords:cabin materials,nonmetallic materials,off-gassing products,GC/MS
