N2 - Both theoretically and experimentally, the effect of temperature has been studied and assessed on analytical characteristics of continuous chromatomembrane gas extraction of volatile organic compounds from aqueous solutions with the aim of their subsequent gas chromatographic determination. It has been found that a rise of temperature up to 80 °C enables reduction of the detection limits of alcohols, ketones, and esters by a factor of 10 to 20. If a water vapor condenser is used in the extractant gas line, then the repeatability of results does not depend on temperature. The conditions have been optimized for the continuous headspace chromatomembrane analysis in combination with gas adsorption (purge and trap) concentration of analytes.
