Introduction

GB/T 19267 is a professional basic standard for forensic scientific trace evidence examination, aiming to improve the quality of identification and unify identification results: Discussion, increase the credibility of identification opinions, and provide norms and guidance for forensic scientific trace evidence examination: GB/T 19267 is planned to consist of 12 parts: ---Part 1: Infrared absorption spectrometry: ---Part 2: UV-visible absorption spectrometry: ---Part 3: Molecular fluorescence spectrometry: ---Part 4: Atomic emission spectrometry: ---Part 5: Atomic absorption spectrometry: ---Part 6: Scanning electron microscopy/X-ray spectroscopy: ---Part 7: Gas Chromatography-Mass Spectrometry: ---Part 8: Microspectrophotometry: ---Part 9: Thin layer chromatography: ---Part 10: Gas Chromatography: ---Part 11: High performance liquid chromatography: ---Part 12: Thermal analysis method: This document is Part 7 of GB/T 19267: It describes the overall principles and basic principles of gas chromatography-mass spectrometry in the examination of trace evidence: The requirements are generally applicable to the physical and chemical examination of trace evidence, and will play an important role in the examination of trace evidence in various cases such as explosions, arson, and gun-related cases: It is used for the standardization and normalization construction of forensic scientific trace evidence examination, improve the quality of identification, unify identification conclusions, and increase the validity of identification opinions: Credibility is important: It has been more than 13 years since the last version of GB/T 19267:7 was released: With the gas chromatography of trace evidence in forensic science- With the development of mass spectrometry testing technology, the content of this standard is no longer applicable to new analytical technologies and methods, and there is also a lack of specific pre-treatment methods for test materials: It is not practical in terms of practicality, identification and expression of results, and needs to be revised and improved urgently: Therefore, this document will be officially launched again in 2021: Revision: Physical and chemical examination of trace evidence in forensic science Part 7: Gas Chromatography-Mass Spectrometry
