This one day course is spent learning the theory of static and dynamic headspace and how to modify samples to improve results, then using this knowledge to create HS methods, analyse samples and experiment with parameters to see the effects.

CC Analytical Services uses the various injection and detection systems available for gas chromatography. This enables delicate substances to be detected in very small amounts. Injection: Liquid Gaseous (dyn. and stat. Headspace) Cool on column

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.

The dimerization of alkanethiol mixtures (hexanethiol, octanethiol, and dodecanethiol) to form self‐assembled monolayers (SAMs) from headspace on nanoporous gold surfaces was studied for the first time using gas chromatography (GC/MS) and time‐of‐flight

Headspace Sampling for Gas Chromatography Headspace sampling is an ideal way of introducing a sample into a GC. It avoids the introduction of involatile or high-boiling contaminants from the sample matrix and it can often be used for the trace or ultra-trace determination of volatile organics with little or no additional sample preparation.
