Abstract

It is known that water vapor present in the atmosphere has an adverse effect on sorption
extraction of analytes while determined by gas chromatography analysis. In the paper, a method of raising
efficiency of sorption concentration of polar organic compounds from moist air has been suggested.
Potassium fluoride is used as a selective sorbent of water vapor. As opposed to calcium chloride that is a
conventional dehydrating agent, potassium fluoride almost does not retain polar organic compounds.
