DVLS Automatic Air Monitoring Analyzer
Measurements of atmospheric concentrations of volatile organic compounds are currently required in both urban and rural environments, where their presence can be directly detrimental to health. The DVLS Automatic Air Monitoring Analyzer (A2MA) Provides in situ Analysis of VOCs in Urban Air.
Automated in situ determination of VOC’s
The A2MA instrument has been developed for the automated in situ determination of airborne volatile organic compounds (VOCs) using programmed temperature vaporisation injection from a sorbent tube trap. A sorbent tube placed as an injection port liner can be repeatedly used to collect samples of air, with the trapped analytes being subsequently desorbed onto a capillary gas chromatography (GC) column without use of intermediate cryogenic refocussing.
The automation of sample collection and the elimination of the intermediate refocussing step, reduces much of the necessary on-site maintenance required for continuous monitoring, and allows in situ analysis in locations where previously this was not possible.
