Estazolam test in suspected drugs
Gas chromatography and gas chromatography-mass spectrometry
1 Scope
This standard specifies the gas chromatography-mass spectrometry (GC-MS) qualitative inspection method and gas chromatography (GC) quantitative inspection method of Estazolam
Principles, reagents and materials, instruments and equipment, operating methods, and result evaluation and presentation.
This standard applies to the qualitative and quantitative analysis of estazolam in solid samples of suspected drugs.
2 Normative references
The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article
Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document.
GB/T 27418 Evaluation and Expression of Uncertainty in Measurement
GA/T 122 Terminology for toxicological analysis
3 Terms and definitions
The terms and definitions defined in GA/T 122 are applicable to this document.
4 Principle
Extract estazolam from solid samples of suspected drugs. Use gas chromatography-mass spectrometry to detect with retention time, characteristic ion fragmentation
The ratio of slice and ion abundance is used as the basis for qualitative judgment; gas chromatographic detection is used, and the chromatographic peak area is used as the quantitative basis.
The internal standard standard curve method is used for quantitative analysis.
5 Reagents
Unless otherwise specified, the reagents used in the analysis are chromatographically pure.
5.1 Methanol.
5.2 Internal standard. Propyl spasmolytic (SKF525A) (purity not less than 95%).
5.3 Standard material stock solution. 1.0mg/mL estazolam standard material stock solution, stored at 0℃~4℃, valid for 12 months.
5.4 Internal standard stock solution for quantitative internal standard curve method. Weigh 500 mg of SKF525A, dilute it with methanol to a 50 mL volumetric flask, and prepare it
10.0mg/mL SKF525A internal standard stock solution. Keep refrigerated at 0℃~4℃, valid for 12 months.
5.5 Standard working solution for qualitative use. Pipette an appropriate amount of estazolam standard substance stock solution, dilute it with methanol, and prepare a 0.1 mg/mL moxa solution.
Stazolam standard working solution. Store at 0℃~4℃, the validity period is 3 months.
5.6 Qualitative control standard working solution. pipette an appropriate amount of estazolam standard substance stock solution, dilute with methanol, and prepare 0.005mg/mL
The standard working solution of estazolam. Store under refrigeration at 0℃~4℃, valid for 1 month.
5.7 Standard working solution for external standard single-point method quantification. pipette an appropriate amount of estazolam standard substance stock solution, dilute with methanol, and prepare
0.1mg/mL estazolam standard working solution. Store at 0℃~4℃, the validity period is 3 months.
