Introduction

1. Standard Overview

This standard (GB/T 42430-2023) specifies the method of using headspace gas chromatography (HS/GC) and headspace gas chromatography-mass spectrometry (HS/GC-MS) to test ethanol, methanol, n-propanol, acetone, isopropanol and n-butanol in blood and urine, which is applicable to the fields of forensic identification and medical testing.

2. Detection principle and method

Based on the volatile characteristics of 6 compounds such as ethanol, qualitative analysis is performed by headspace gas chromatography or headspace gas chromatography-mass spectrometry. Quantification is performed by internal standard method or external standard method, and calibration is performed in combination with standard substances.

Compound Name	Retention Time (min)	Characteristic Fragment Ions (m/z)
Acetone	1.74	74*, 58, 42
Methanol	2.19	31*, 29, 32
Isopropyl Alcohol	2.48	59*, 43, 67
1-propanol	3.89	73*, 42, 59
1-butanol	5.21	93*, 56, 41

3. Background of Standardization and Analysis of Technological Evolution

This standard is under the jurisdiction of the National Technical Committee on Criminal Technology Standardization, and the main drafting units include the Forensic Science Research Institute, the Identification Center of the Ministry of Public Security, etc. The standard is based on the latest advances in headspace gas chromatography and mass spectrometry, and is designed to improve detection sensitivity and accuracy.

4. Implementation recommendations

To ensure the effective implementation of the standard:

Laboratories should be equipped with gas chromatographs and mass spectrometers that meet the requirements, and calibrate the equipment regularly.
Operators should receive professional training and be familiar with headspace gas chromatography and mass spectrometry.
It is recommended to establish a quality control system to ensure the reliability and consistency of test results.
