• Description:
  An effort was made to improve several routine gas chromatographic separations currently performed using packed columns or nonoptimized open tubular columns. The suggested improvements provided column operating conditions optimized for speed and a minimized injection band width. The system was evaluated using common organics such as alkanes, aromatics, alcohols, ketones, and chlorinated hydrocarbons. For all tested compounds quantitative trapping and reinjection was achieved. For many compounds the limits of detection were less than 1 part per billion. Use of the cold trap inlet with a low dead volume detector and a high speed electrometer indicated that the efficiency available from commercial capillary columns can be better utilized. Retention times may be reduced for some routine separations to a few seconds.
