36 Chapter 2 Fig. 2-5, the separation of all 16 hydrocarbons is fairly good. High-speed gas chromatographic analysis of low molecular weight hydrocarbons and some chlorinated methanes with ALOT columns was investigated by Peters and Saks . In their work relatively short length ALOT columns ( 2 . M . O m) are operated with hydrogen carrier gas at an average linear velocity of about 150 cm/s. A highspeed gas value inlet system is used to produce inlet band-widths of less then 5 ms. Also a highspeed electrometer is used for data collection.
