【 摘 要 】

The possibilities of using a semiconductor multisensor device as a detector for gas chromatography are considered. Semiconductor films of various compositions were investigated for their performance as sensors, the optimal composition for inertia and sensitivity was established. The basic parameters of the detector were determined: sensitivity, linear dynamic range, detection limit. The applicability of the detector for solving typical problems of capillary gas chromatography is shown. Two methods for the identification of organic compounds using a detector based on three sensors have been proposed.
