Diffusive Monitoring – A Cost-Effective and Quantitative Approach to Environmental Monitoring

In this poster, thermally desorbed diffusive tubes have been shown to be viable ambient air samplers. Their sampling mechanism is well understood/validated, and TD-GC(MS) analytical methods developed for pumped sorbent tubes can be applied. They offer several advantages over pumped sorbent tubes in terms of simplicity, reduced variability, cost, extended sampling times and minimal water interference
