Monitoring of the Drying Process by Direct Solid-Phase Microextraction

Abstract

SPME is known as a rapid and convenient method for analyzing air-borne organic compounds in closed systems ('headspace SPME'). In this investigation we have applied this technique to the monitoring of the drying process of chemicals containing small amounts of organic solvents under specific conditions. Interesting results were found and some of them are presented and discussed in this paper.
