This application note reviews indoor and outdoor air monitoring of volatile organic compounds (VOCs) using tube type diffusive samplers and thermal desorption (TD)–GC analysis. Specific attention is paid to general sampling/analytical procedures, concentration/detection limits, applicable analyte ranges, minimizing artefacts, quality assurance and method limitations.

This Application Note describes validation of an on-line thermal desorption–mass spectrometry (TD–MS) system for rapid measurement of sub-ppb levels of VOCs in industrial carbon dioxide.

Diffusive monitoring is widely used in all air monitoring scenarios, i.e. occupational hygiene plus indoor air and ambient air monitoring. By eliminating the requirement for a sampling pump, diffusive monitoring provides a simple and cost-effective method of collecting the large number of samples required in many air monitoring programmes.

In this application note, Markes International show how Markes’ TD technology is compatible with trace-level sulfur compounds, both in standard mixes and in real-life samples.
