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.

What You Will Learn

  • Overview of the different types of adsorbents suitable for thermal desorption
  • The role that size and shape of the adsorbents play in collection of the air sample
  • Which adsorbents are truly hydrophobic
  • How moisture in the air can affect the performance of the adsorbents
  • Recommended flow rates and sample volumes for different sampling conditions
