Application Note: Monitoring ‘Air Toxics’ in Ambient Air using Sorbent Tubes by Automated, Cryogen-Free Thermal Desorption in Accordance with US EPA Method TO-17
7 August 2014

This Application Note demonstrates the fundamental sensitivity of Markes’ ULTRA–UNITY system for the analysis of TO-17 ‘air toxics’ ranging in volatility from chloromethane to hexachlorobutadiene. Also highlighted is the ability of Markes’ ClearView background-compensation software to improve signal-to-noise ratios and enhance spectral purity for trace-level compounds.
