The EPA purge and trap method is widely accepted as the method of choice for routine analysis of volatile organic compounds (VOC) in water. Recently, Pankow and Rosen summarized the status of this method and suggested a new variation involving direct purging to a capillary column. Their method avoids potential problems associated with the use of a sorbent trap and reduces the overall time required for analysis, but retains the conventional purge cycle. The purpose of this paper is to suggest an alternative approach that eliminates the purge cycle and permits direct injection of water samples to a capillary column.
