Choosing the Right Adsorbent for Your Thermal Desorption Gas Chromatography Applications

What Does It Cover?

This webinar provides an overview of adsorbents that are suitable for thermal desorption (TD), and the factors you need to consider when selecting an adsorbent. The presentation provides details about adsorbent mesh sizes, surface area, and temperature limits; and how these parameters influence the sample collection process. This webinar also covers the use of single and multi-bed tubes, as well as recommendations for sample volumes and sampling flow rates to assist in method development.

Selecting the best suited adsorbent(s) is an important factor in achieving the desired sensitivity and selectivity for an application, and this webinar will provide you with the information you need to optimize your method.
