What is thermal desorption?
A guide to the history, principles and applications of thermal desorption for gas chromatography
Analytical thermal desorption (TD) is a sample preparation and introduction technique for gas chromatography (GC) that overcomes the drawbacks of conventional sample preparation techniques, such as solvent extraction, solid-phase micro-extraction, purge-and-trap and static headspace.
Advantages of thermal desorption include:
- Greater sensitivity than conventional sample preparation techniques.
- Applicability to a wider range of compound classes and sample types.
- It is safer and more environmentally friendly than solvent extraction.
- It is more easily automated and validated.
- TD is compliant with key standard methods.
Key applications of thermal desorption
All this and key applications of TD are explained simply and clearly in the What is thermal desorption? e-book. In just 24 pages, this easy-to-read guide explains how TD works, along with important aspects such as sorbent choice and sampling options.
