Volatiles Organic Sampling Train Fundamentals (VOST)

About this webinar:

The EPA considers the volatile organic sampling train (VOST) an essential medium for the characterizations of stack gas compounds boiling between 30C and 131C.  This generally includes the compounds between Freon 11 and chlorobenzene, which are considered candidate target analytes that can be sampled and analyzed by the VOST method.

This presentation will provide a review of the fundamental concepts of VOST sampling and analysis that affect final data quality and defensibility.  Some data artifacts that often occur during VOST testing, including background contamination and breakthrough, will be presented with some laboratory observations and recommendations that should be helpful to a test team to ensure defensible data is acquired.

Topics the presentation will cover:

• Fundamentals of VOST
• Sampling affects on data quality
• Contamination and Breakthrough during sampling
• Ensuring defensible data

Who should attend?

• Commercial and Industrial companies
• Consulting and Engineering firms
• Federal, State and Municipal entities

A question and answer session will immediately follow the presentation. At the conclusion of each webinar, you will be asked for your feedback and opinions for future webinar topic to be developed by TestAmerica.
