Forensic science tests tramadol in suspected drug
Liquid Chromatography and Liquid Chromatography-Mass Spectrometry
1 Scope
This document specifies the liquid chromatography-mass spectrometry (LC-MS) qualitative testing method and liquid chromatography method for tramadol in suspected drugs in the field of forensic science.
Spectrum (LC) quantitative testing method.
This document is applicable to the qualitative and quantitative analysis of tramadol in suspected drugs in the field of forensic science.

GB/T 6682 Specifications and test methods for water used in analytical laboratories
GB/T 27418 Evaluation and expression of measurement uncertainty
GA/T 122 Toxicological analysis terminology
3 Terms and definitions
The terms and definitions defined in GA/T 122 apply to this document.
4 Principles
Extract tramadol from suspected drugs (see Appendix A for relevant information). Liquid chromatography-mass spectrometry was used for detection, with retention time,
The characteristic ion pairs and ion pair abundance ratio of mass spectrometry are used as the basis for qualitative judgment; liquid chromatography is used for detection, and the chromatographic peak area is used as the basis for quantitative judgment.
According to the data, quantitative analysis was carried out using the external standard single point method or the external standard standard curve method.
5 Reagents and materials
5.1 Reagents
The experimental water should comply with the first-class water specified in GB/T 6682.Unless otherwise stated, the reagents used in the analysis are of chromatographic grade.
Reagents include.
a) methanol;
b) 20% phosphoric acid solution (taking 10 mL as an example). Take 2 mL of concentrated phosphoric acid (analytically pure, mass fraction 88%), and dilute with water
to 10mL;
c) Phosphate buffer solution (take the preparation of 1000mL as an example). weigh 31.21g of sodium dihydrogen phosphate dihydrate and dissolve it in 800mL of water;
Add 2mL triethylamine, adjust the pH value to 3.5 (±0.2) with 20% phosphoric acid solution, add water to make the volume to 1000mL, and use vacuum
Suction filtration with a suction filtration pump, ultrasonic treatment with an ultrasonic cleaner, and it is ready for use;
