开发了一种简单、功率要求最低的GC系统，用于测定微生物呼吸气体：H_2、N_2、O_2、CH_4、CO_2和内标Kr。这样的系统将被用于生命探测设备，考虑在火星上着陆。该系统由填充了磷酸处理的Porapak Q的色谱柱组成，并与微珠热敏电阻检测器一起保持在20℃，为测定微生物呼吸气体提供了一种灵敏的手段。
A simple GC system with minimal power requirements was developed for determining the microbial-respiratory gases: H2, N2, O2, CH4, CO2, and Kr—an internal standard. Such a system would be used in a life detection device to be considered for landing on Mars. The system, consisting of a column packed with phosphoric acid-treated Porapak Q and maintained at 20°C in conjunction with a microbead thermistor detector, provided a sensitive means of determining microbial-respiratory gases.
