1 Scope
This standard specifies the benzodiazepines (brozepam, chlordiazepoxide, diazepam, estazolam and triazole) in suspected drugs in the field of forensic science.
Liquid chromatography-mass spectrometry (LC-MS) qualitative test method and liquid chromatography (LC) quantitative test method.
This standard applies to benzodiazepines (brazepam, chlordiazepoxide, diazepam, estazolam and triazole) in suspected drugs in the field of forensic science
Qualitative analysis and quantitative analysis.
