ELEMENTS OF QUALITY ASSURANCE IN MONITORING VOLATILE ORGANIC COMPOUNDS AT TRACE LEVELS
Citation:
McClenny, W A. ELEMENTS OF QUALITY ASSURANCE IN MONITORING VOLATILE ORGANIC COMPOUNDS AT TRACE LEVELS. Presented at 14th Annual Quality Assurance Conference, Dallas, TX, October 18-22, 2004.
Impact/Purpose:
Develop innovative and customized new measurement approaches for air toxic VOCs as requested by methods development clients.
Description:
Monitoring for air toxic VOCs at sub-ppbv concentrations has been demonstrated in the TO-15 Supplement recently published by the EPA. While this approach uses specially prepared canisters for sampling and storage of the air samples, the use of solid adsorbents has now been investigated for the same purpose. Examples of the results obtained with both canisters and solid adsorbents are given along with a discussion of the quality assurance guidelines in both cases.
Although this work was reviewed by EPA and approved for publication, it may not necessarily reflect official Agency policy.
