Headspace analysis is a technique to separate, collect, and analyze volatile compounds from different sample matrixes such as water, solids, and fruits. Headspace analysis has divided in two techniques: dynamic and static. Dynamic headspace utilizes “purge and trap” to enrich the volatiles on a sorbent more efficiently while Static headspace is simple and provides a cost effective way to collect VOCs. This headspace anlaysis is widely used with GC in the analyses of alcohols in blood, analyses of monomers in polymers and plastics, flavors in food, beverages and perfumes. A needle trap device (NTD), like solid-phase microextraction (SPME) fibers, is another approach for one-step solventless sample preparation and injection technique for GC. The major advantages of NTD, as a sorbent trap technique, are simplicity and convenience for sampling and injection. We utilized a stand type, step motored syringe pump to develop headspace sampling technique for analyzing VOCs in liquid samples especially for NTDs. In this report, mainly static headspace sampling technique will be introduced but dynamic headspace sampling technique reported several years ago will be presented also.
