Forensic ethyl glucose in blood and urine
Glycoside inspection gas chromatography-mass spectrometry and
Liquid chromatography-mass spectrometry
1 Scope
This standard specifies gas chromatography-tandem mass spectrometry (GC-MS/) for ethyl glucuronide (EtG) in forensic blood and urine
MS), liquid chromatography-tandem mass spectrometry (LC-MS/MS) qualitative and quantitative testing method.
This standard applies to qualitative and quantitative analysis of ethyl glucuronide in forensic blood and urine. Among other suspicious samples
The qualitative analysis and quantitative analysis of ethyl glucuronide can be used by reference.
2 Normative references
The following documents are essential for the application of this document. For dated references, only the dated version applies to this article
Pieces. For the cited documents without date, the latest version (including all amendments) applies to this document.
GB/T 6682 Analysis laboratory water specifications and test methods
GA/T 122 Nomenclature of poison analysis
3 Terms and definitions
The terms and definitions defined in GA/T 122 apply to this document.
4 Principle
Using blank samples and added samples as controls, extract blood and urine according to the requirements of parallel operation (gas chromatography-tandem mass spectrometry)
Derivatization is required before analysis). After gas chromatography-tandem mass spectrometry and liquid chromatography-tandem mass spectrometry, the qualitative quantitative analysis is used to determine the retention time and quality.
Spectral characteristic ions and relative abundance ratio were used as the basis for qualitative judgment; based on the peak area, the internal standard method was used for quantitative analysis.
5 Reagents and materials
5.1 Reagent
The water for gas chromatography-mass spectrometry experiment should meet the third grade water specified in GB/T 6682, and the water for liquid chromatography-mass spectrometry experiment should meet
Grade 1 water specified in GB/T 6682.Unless otherwise stated, the reagents used in the analysis are of analytical grade, and the reagents include.
a) Methanol (chromatographically pure);
b) Acetonitrile (chromatographically pure);
c) BSTFA (bistrimethylsilane trifluoroacetamide)/T MCS (trimethylchlorosilane) mixed solution (volume ratio 99.1);
d) anhydrous pyridine;
e) 50% formic acid solution (chromatographically pure);
