Test of Dimethylene Dioxyamphetamine 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 of dimethylene dioxyamphetamine (MDMA)
The principle, reagents and materials, instruments and equipment, operation methods, and result evaluation and expression of the quantitative test method of spectroscopy (GC).
This standard applies to the qualitative and quantitative analysis of MDMA 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.

3 Terms and definitions
The terms and definitions defined in GA/T 122 are applicable to this document.
4 Principle
Extract MDMA from solid samples of suspected drugs. Use gas chromatography-mass spectrometry to detect
The ratio of slice and ion abundance is used as the basis for qualitative judgment; gas chromatography is used to detect, and the chromatographic peak area is used as the quantitative basis, and the external standard single-point method or
The internal standard standard curve method was 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. n-decane (purity not less than 95%).
5.3 Standard material stock solution. 1.0mg/mLMDMA standard material stock solution, stored at 0℃~4℃, valid for 12 months.
5.4 Internal standard stock solution for quantification by internal standard standard curve method. Weigh 500 mg of n-decane and dilute it with methanol into a 50 mL volumetric flask to prepare
10.0mg/mL n-decane internal standard stock solution. Keep refrigerated at 0℃~4℃, the validity period is 3 months.
5.5 Standard working solution for qualitative use. Pipette an appropriate amount of MDMA standard substance stock solution, dilute with methanol, and prepare a 0.1 mg/mL solution.
MDMA standard working solution. Keep refrigerated at 0℃~4℃, the validity period is 3 months. Qualitative standard work for other concentrations used in the experiment
The solutions are all obtained by diluting the standard substance stock solution with methanol.
5.6 Qualitative control standard working solution. Pipette an appropriate amount of MDMA standard substance stock solution, dilute with methanol, and prepare 0.002mg/mL
MDMA standard working solution. Store under refrigeration at 0℃~4℃, the validity period is 1 month.
5.7 Standard working solution for external standard single-point method quantification. pipette an appropriate amount of MDMA standard substance stock solution, dilute with methanol, and prepare
