T/ZJATA 0027-2025 Determination of 39 kinds of narcotic drugs, psychotropic drugs and their metabolites in domestic wastewater by liquid chromatography-tandem mass spectrometry method

Scope

Scope: This document describes the liquid chromatography-tandem mass spectrometry method for the determination of 39 kinds of narcotic drugs, psychotropic drugs, and their metabolites in domestic wastewater samples. This document is applicable to the determination of 39 kinds of narcotic drugs, psychotropic drugs, and their metabolites in domestic wastewater samples by liquid chromatography-tandem mass spectrometry. Main technical content: The standard includes the principles of the test method for determining 39 kinds of narcotic drugs, psychotropic drugs, and their metabolites in domestic wastewater, reagents or materials, instruments and equipment, analysis steps (including sample pretreatment), quality control, data processing, and precision. It specifies the liquid chromatography-tandem mass spectrometry method for the determination of 39 kinds of narcotic drugs, psychotropic drugs, and their metabolites in domestic wastewater. After filtering the wastewater samples, they are purified using a mixed strong cation exchange extraction column, separated by liquid chromatography, and detected by multiple reaction monitoring (MRM) mode of tandem mass spectrometry. Qualitative analysis is performed by comparing with blank samples and added samples in parallel operations based on retention time, characteristic ion pairs, and ion pair abundance ratio. Quantitative analysis is based on the peak area of quantitative ions. The standard is advanced and innovative, and conforms to the key directions of group standard construction.
