DYNAMIC HEADSPACE VACUUM TRANSFER 'IN TRAP' EXTRACTION METHOD AND APPARATUS

摘要

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, said method comprising extracting the headspace by sucking volatile compounds into a sorbent comprising trap followed by desorption into the injector of a GC-MS analyzer.
