Addressing the challenges of collecting and analyzing VOCs in ambient air.

TO-15 is a performance-based method prepared by the EPA as a guidance document for monitoring subsets of those volatile organic compounds (VOCs) that are mentioned in Title III of the Clean Air Act Amendments of 1990. The EPA method used to test VOCs is with canister collection methods and analyzed using a GC/MS.

Metiri Group labs use stainless steel canisters (summas), Tedlar bags, and Bottle-Vacs for TO-15 sample collection, with the most common contaminated sites being gas stations, car stores, auto shops, dry cleaners and printing presses. It's not uncommon for Metiri Group laboratories to process 750 samples in one month. Offering their expertise to consultants, municipalities, regulatory agencies and industrial facilities.
