A simplified purge and cryotrap method for the analysis of trace aqueous halocarbons is described. The usual Tenax® adsorption trap is replaced with a cryoloop preceded by a permeation dryer which selectively removes water vapour and thereby prevents freezing in the cryoloop. This "one-step" method reduces potential contamination and is highly sensitive when coupled with capillary electron capture detector analysis of the purged volatiles. Using this method several previously unreported halocarbons have been observed in natural waters. Furthermore, Henry's law constants can be calculated directly by analysing both water and ambient air samples collected at the same time. © 1984.
