Abstract
The effect of temperature on the analytical characteristics of the continuous chromatomembrane gas extraction of volatile organic compounds from aqueous solutions for their subsequent gas-chromatographic determination is studied theoretically and experimentally. It is found that an increase in temperature to 80°C lowers the detection limits of analytes by several times and significantly improves the performance of the gas-extraction system. The repeatability of the results does not depend on temperature when a water vapor condenser is used in the line of extraction gas.
