Gas chromatography of Titan's atmosphere

摘要: Abstract An alternative for the GC determination of permanent gases in Titan's atmosphere, given severe constraints space instrumentation, is use a 100–120-mesh molecular sieve 5A micropacked column. Because its high efficiency, small pressure drop and short analysis time, such column fully compatible with experimental Cassini-Huygens mission. In order to optimize conditions associated this column, methodological approach was supported by Doehlert design. With optimized conditions, provides rapid separation selected products under isothermal about 900 theoretical plates per metre at 70°C most solutes studied.
