EPA Method TO-15 is the procedure used to analyze air samples collected through canister sampling. “TO” stands for “toxic organics.” It is used to measure up to 97 volatile organic compounds (VOCs) of the total 189 hazardous air pollutants listed in the Clean Air Act. It is used for testing grab samples of ambient air, including bucket samples.
