Analysis of Polar and Non-Polar VOCs From Ambient and Source Matrices: Development of a New Canister Autosampler Which Meets TO-15 QA/QC Criteria
Approximately 108 of the Hazardous Air Pollutants (HAPs) specified in the 1990 Clean Air Act Amendments are classified as volatile organic compounds (VOCs). Of the 108 VOCs, nearly 35% are oxygenated or polar compounds. While more than one sample introduction technique exists for the analysis of these air toxics, SUMMA® canister sampling is suitable for the most complete range of analytes. A broad concentration range of polar and non-polar species can be analyzed from canisters.
A new canister autosampler, the Tekmar AUTOCan autosampler, has been developed which incorporates the autosampler and concentrator into a single unit. Analysis of polar and non-polar VOCs has been performed. This paper demonstrates adherence to the technical acceptance objectives outlined in the TO-15 methodology including initial calibration, daily calibration, blank analysis, method detection limits and laboratory control samples. The analytical system consists of a Tekmar AUTOCan autosampler interfaced to a Hewlett Packard 5890/5972 MSD.
