Day 3 / Modules 7 – 8 of the Complete GC & GC-MS and the Practical Essentials of GC & GC-MS courses.

You will learn about mass spectra and library searching and how to undertake data analysis. We look at reasons for performing the analysis: qualitative analysis, identification, quantitation and semi-quantitation are covered.

Following this, we cover sampling techniques, where a whole range of sampling and sample preparation techniques that can be coupled to a GC are covered in detail, including their theory, optimisation and applications.

The techniques include thermal desorption (TD) & extraction; pyrolysis; derivatisation; static & dynamic headspace (SHS & DHS); purge & trap; solid phase extraction techniques including solid-phase microextration (SPME), SPE & SBSE; liquid-liquid extraction techniques and other automated methods.
