Abstract
The studies were performed to determine the possibility of application of potassium carbonate and calcium chloride to dry a stream of atmosp heric air before enriching analytes of monoterpens group. It was found out that 80 to 90% of water vapour content can be removed from air ne arly completely saturated with water vapour. The losses of monoterpene analytes does not exceed 10% and are independent of gas humidity. The recovery of analytes decreases with analyt concentration and temperat ure drop of dried air stream.
