Abstract
This is a review article concernning the development of a gas chromatographic analytical method for the analysis of 70 air toxic compounds. Not only the operating conditions, but also the column system is optimized. Optimization of the GC analytical methods for air toxic compounds is based on a unified method with a system comparising two columns. An optimization strategy with stepwise temperature programming has been used to achieve optimum separations. Two sets of usual GC instruments with specially developed software, Chromatogram Analyzer, have also been used for this purpose. Some essential retention data and typical results are presented in this paper.
