Designed the installation of the circulating vapor-phase analysis in combination with gas-liquid chromatography and infrared spectroscopy. The schematic diagram of the installation, its main elements, the mechanism of operation. The light commercial oil products circulating at the oil and gas facilities were investigated. The proposed method of vapor-phase analysis of flammable liquids allows solving criminalistic problems of hierarchy detection-diagnosis-identification in the study of emergency fire situations at oil and gas facilities.
