Utilizing Automated Cryogen-Free Thermal Desorption to Monitor Air Toxicity

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.
