Simultaneous Cryogen-Free Analysis of PAMS Ozone Precursors and TO-15 Air Toxics from Canisters

This application note describes cryogen-free sampling and analysis of PAMS ozone precursors and TO-15 air toxics in high-humidity environments, in compliance with new Chinese air-monitoring regulations. The use of Markes’ groundbreaking Dry-Focus3 preconcentration and water management technology results in excellent chromatographic peak shape at 100% humidity, whilst maintaining sample-to-sample cycle times below 60 minutes.
