Foreword

GB/T 18294 "fire technology identification method" is divided into six parts. - Part 1. Ultraviolet spectroscopy; - Part 2. Thin layer chromatography; - Part 3. Gas Chromatography; - Part 4. High performance liquid chromatography; - Part 5. Gas chromatography - mass spectrometry; Part 6. Infrared spectroscopy. This part is part 5 of GB/T 18294. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part is made by the Ministry of Public Security of the People's Republic of China. This section is headed by the National Fire Safety Standardization Technical Committee Fire Investigation Subcommittee (SAC/TC113/SC11). This part of the drafting unit. Ministry of Public Security Tianjin Fire Research Institute. The main drafters of this section. Tian Guihua, Lu Zhibao, Deng Zhenyu, Liang Guofu, Geng Huimin. Fire technology identification method Part 5. Gas chromatography - mass spectrometry

1 Scope

This part of GB/T 18294 specifies the terms and definitions of gas chromatography-mass spectrometry (GC-MS) in fire technology identification. Test equipment, test conditions and test methods. This part applies to gasoline, kerosene, diesel, paint thinner and other fire scene common flammable liquid and its combustion residue identification.

2 normative reference documents

3 terms and definitions

GB/T 19267.7 and GB/T .20162 and the following terms and definitions apply to this document. 3.1 Total ion chromatogram total ionchromatogram In the chromatographic conditions under which the flammable liquid is passed through a capillary column, the total ion current of each component obtained by mass spectrometry The intensity varies with the scan time. 3.2 Extraction of ion - flow chromatograms extractedionchromatogram A map of the characteristic ion peaks of the flammable liquid selected from the total ion chromatogram.

4 test principle

After the laboratory pretreatment to be analyzed samples, injected into the gas chromatography-mass spectrometry instrument, after a pair of analytical samples with good Good separation of the capillary column into the mass spectrum, the total ion chromatogram, using the total ion chromatogram and extraction of ion current chromatography The characteristic of the flammable liquid is determined qualitatively by distinguishing the characteristic peaks.
