Brucine and strychnine in forensic biological samples
Inspection liquid chromatography and liquid chromatography-mass spectrometry
1 Scope
This standard specifies the liquid chromatograms of strychnine and strychnine in forensic scientific biological samples (blood, urine, liver, kidney, stomach and stomach contents, etc.)
(HPLC) quantitative test method and liquid chromatography-mass spectrometry (LC-MS) qualitative and quantitative test method.
This standard is applicable to the qualitative and quantitative analysis of brucine and strychnine in forensic biological samples. Other suspicious samples in Malaysia
The qualitative analysis and quantitative analysis of Qianzijian and Strychnine 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, according to the requirements of parallel operation, extract, purify and concentrate biological samples, using high-efficiency liquid
Quantification by phase chromatography, legal quantification by liquid chromatography-mass spectrometry, with retention time, characteristic ions of mass spectrometry and relative abundance ratio as qualitative judgment criteria
According to the peak area, the external standard method was used for quantitative analysis.
