Miniaturization of enantioselective gas chromatography.
In the context of the Titan Chiral Organics Explorer (TCOE) mission, the theoretical and practical aspects of the miniaturization of enantioselective gas chromatography are discussed. The use of short columns (0.5-10 m) with a conventional inside diameter of 250 microm is proposed. The inside diameter should be increased for vacuum-assisted GC-MS using a restrictor at the inlet of the capillary. The feasibility of cryogenic enantioselective gas chromatography is demonstrated. The hitherto elusive use of chiral mobile phase additives in enantioselective gas chromatography is proposed.
