Title: Passive monitoring of VOC in air using ACC. Final report, revised edition

The report describes a project that developed a method of using activated carbon cloth (ACC) as a sampler for measuring volatile organic compounds (VOCs) in air. Strips of carbon cloth mounted in slide holders were tested as diffusive samplers exposed to known concentrations of standard chemicals in test chambers. Adsorbed chemicals were extracted with solvents and analyzed, and comparison was made between the results obtained with the cloths and with passive samplers. Preliminary tests were carried out to determine the effects on carbon cloth performance of relative humidity, methods of extraction, materials for storing the cloth strips, and the type of cloth. Appendices include tables of experimental data and a report on a novel method of solventless extraction based on a combination of solid phase micro-extraction and purge/trap methods.
