Inspection of phosphine in forensic biological samples Headspace gas chromatography and headspace gas chromatography-mass spectrometry1 ScopeThis standard specifies the headspace gas chromatography (HSGC) quantitative detection of phosphine in biological samples (blood, urine, liver, kidney, stomach and stomach contents, etc.) Qualitative and quantitative inspection method of headspace gas chromatography-mass spectrometry (HSGC-MS). This standard applies to qualitative and quantitative analysis of phosphine in biological samples. Qualitative analysis and determination of phosphine in other suspicious samples Quantitative analysis can refer to use.2 Normative referencesThe 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 analysis3 Terms and definitionsThe terms and definitions defined in GA/T 122 apply to this document.4 PrincipleThe blank sample and the added sample were used as controls. According to the requirements of parallel operation, headspace gas chromatography-mass spectrometry was used for quantification. Chromatographic quantification, based on retention time, characteristic ion fragment peak of mass spectrometry and relative abundance ratio as qualitative judgment basis; based on peak area, use external Standard method for quantitative analysis.5 Reagents and materials5.1 Reagent The water used for the experiment shall conform to the third grade water specified in GB/T 6682.The reagents used in the analysis are of analytical grade, and the reagents include. a) 20% sulfuric acid solution. take 20mL concentrated sulfuric acid and slowly add it to 80mL water; b) Zinc powder (no arsenic); c) Standard solution. 1) Sodium hypophosphite standard solution (equivalent to 1.0 mg/mL containing phosphine). accurately weigh sodium hypophosphite (NaH2PO2 H2O) Standard substance 155.90mg, dissolved in a small amount of water, diluted to 50mL, formulated to contain phosphine equivalent The 1.0 mg/mL sodium hypophosphite standard solution was placed in the refrigerator and stored in a refrigerator. Valid for 1 month. 2) Sodium hypophosphite working solution (equivalent to 0.1mg/mL containing phosphine). Pipette sodium hypophosphite standard solution (equivalent to containing Phosphine 1.0mg/mL), diluted with water to 10mL, sealed, placed in the refrigerator and stored in the refrigerator, valid for 7 days. experiment ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GA/T 208-2019_English be delivered?Answer: Upon your order, we will start to translate GA/T 208-2019_English as soon as possible, and keep you informed of the progress.
