How to Shorten Cycle Times for USEPA Method 524.3 Using the Evolution 2 Purge and Trap Concentrator

The United States Environmental Protection Agency released Method 524.3 with some changes that incorporated some of the advances in purge and trap technology. One of those modifications allowed for the purge flow and time to be revised in order to make the purge and trap cycle times shorter and allow laboratories to be able to test more samples. This application will examine two different purge flows and times and compare the corresponding results.
