This Part II of the article reviews information in the literature on air-sampling techniques commonly used for monitoring volatile organic compound (VOC) levels in atmospheric air. It describes containers for collecting samples of atmospheric air (e.g., vacuum canisters and bags made from synthetic materials). It discusses dynamic, passive and denuder techniques for sampling analytes from air combining isolation with preliminary enrichment, and also miniaturized instruments for extracting VOCs. We compare the parameters of selected ex situ analytical techniques and automatic monitoring instruments.
