A sampling method for very volatile organic compounds (VVOCs) using carbonaceous multi-bed sorbents

A sampling strategy was evaluated to determine emissions of very volatile organic compounds (VVOCs) from building products in environmental test chambers. The test chamber was doped with a mixture of 21 VVOCs. A sampling method for active air sampling was developed using two carbon molecular sieve sorbents, i.e., Carbograph 5TD and Carbopack X, by variation of sampling parameters such as sampling volume and air flow rate.
