Introduction

Hypnotics and sedatives are a common class of drug poisons in toxicological analysis, with many types and great differences in physicochemical properties. This document provides for the Court Section A liquid chromatography-mass spectrometry screening method for 46 hypnotics and sedatives such as barbiturates in biological samples (blood, urine), aiming to improve the analytical efficiency rate and ensure the quality of the analysis. GA/T 1902 is intended to consist of two parts. --- Part 1.Gas chromatography-mass spectrometry; --- Part 2.Liquid chromatography-mass spectrometry. 46 kinds of barbiturates in forensic biological samples Screening of sedative and sedative drugs Part 2.Liquid Chromatography-Mass Spectrometry

1 Scope
