Increase of headspace volume will favor analytes to volatilize towards headspace gas phase; however, overlarge headspace volume will ''dilute'' analytes and therefore decrease sensitivity. Also, it is known that the larger sample volume is in the headspace vial, the more the increase in the amounts of analytes.

2006/4/18 · Static Headspace-Gas Chromatography: Theory and Practice has long been the only reference to provide in-depth coverage of this method of analysis. The Second Edition has been thoroughly updated to reflect the most recent developments and practices, and also includes coverage of solid-phase microextraction (SPME) and the purge-and-trap technique.

A headspace gas chromatographic (GC) method, which can be automated, has been developed for determination of methyl bromide. This method has been applied to wheat, flour, cocoa, and peanuts. Samples to be analyzed are placed in headspace sample vials, water is added, and the vials are sealed with Teflon-lined septa.
