| Abstract |
A number of support-bonded liquid phase sorption media were developed and evaluated in model systems for collecting and analyzing organic air pollutants. Polymers with various functional groups were synthesized and chemically bonded onto inert supports in thick layers. A media consisting of a silicone liquid bonded to Chromosorb W was used with excellent results. Retention times of most organic compounds on this liquid are extremely long at ambient temperatures, and sampling can be carried out for 24 hours at a rate of 10 liters of air per minute. In contrast, subsequent counter current liquid extraction takes only a few minutes since retention volumes are very small. Extracts were analyzed largely by gas chromatography. |
