Abstract
A headspace extraction and analysis method for volatile compounds can be performed in automatic mode in a HS-ITEX apparatus adapted to be additionally connectable to a vacuum source. The method includes extracting the headspace by sucking volatile compounds into a sorbent-containing trap followed by desorption into the injector of a GC-MS analyzer.
