Application Note: EPA Method TO-17 for Monitoring ‘Air Toxics’ in Ambient Air using Sorbent Tubes and Automated, Cryogenfree Thermal Desorption
3 June 2014

This application note demonstrates the fundamental sensitivity of the series 2 ULTRA UNITY Air Toxics Analyzer configuration run with GCMS. Quantitative detection of TO-17 ‘air toxics’ ranging from methyl chloride to hexachloro-1,3-butadiene is shown down to 0.1 ppb on sorbent tubes and even lower levels would be possible by using the MS in SIM mode or sampling larger air volumes.
