Sample throughput is often a critical bottleneck for thermal desorption tube (TDT) analysis in the contract testing or research laboratory. By coupling in-line thermal desorption (TD) with selected ion flow tube mass spectrometry, throughputs of up to 20 tubes per hour can be achieved per instrument.

This webcast will introduce SIFT-MS, a direct mass spectrometry technique that provides real-time detection of volatile organic compounds and many inorganic gases to sub-part-per-billion concentrations (by volume; ppbV), and explain the rationale behind seamlessly integrating TD with SIFT-MS. In short, the benefits of coupling TD and SIFT-MS are economic distributed sampling (such as for US EPA Method 325) and much higher throughput for an industry-standard sampling media. Analytical performance of TD-SIFT-MS will be described together with a variety of case studies drawn from:

  • Vehicle interior air quality (VIAQ) analysis
  • Environmental monitoring
  • Breath research

Key Learning Objectives:

  • Learn the fundamentals of the SIFT-MS technique and the benefits of fully integrating thermal desorption
  • Observe the throughput gains achievable with SIFT-MS for a variety of routine and research lab applications
  • Learn how automated thermal desorption analysis using SIFT-MS provides new application and product insights due to simultaneous desorption and analysis
