These changes are within the audit accuracy of 30% specified in EPA Compendium Method TO-17, “Determination of Volatile Organic Compounds in Ambient Air Using Active Sampling onto Sorbent Tubes (U.S. EPA, 1999b). People breathe approximately 20,000 liters of air a day so this concern is significant. The U. S. Environmental Protection Agency (EPA) has reported that vacuum distillation can be used to determine the concentration of volatile organic compounds (VOCs) in various matrices. A method involving methanol solvent extraction (SE) and purge and trap (PT) was evaluated for the determination of chlorinated volatile organic compounds (VOC) in sediments. 2.12 US EPA Method 24, Determination of Volatile Matter Content, Water Content, Density, Volume Solids, and Weight Solids of Surface Coatings, Title 40 Code of 310 method and EPA 24 method both rely on indirect determination of the VOCʼs and require several steps. You may need a PDF reader to view some of the files on this page. A sample integrity evaluation and an interlaboratory comparison were conducted in application of U.S. Environmental Protection Agency (EPA) Methods 325A and 325B for diffusively monitoring benzene and other selected volatile organic compounds (VOCs) using Carbopack X sorbent tubes. The range of compounds analyzed by the method depends on the selection of the sorbent cartridge. 1.3 This method can be used to quantitate most volatile organic compounds that have boiling points below 200 EC.
