T/SZAEM 0004-2025 Determination of 6PPD-quinone in water Online solid phase extraction-Liquid chromatography-mass spectrometry method

Scope

This standard is applicable to the determination of 6PPD-quinone (N-(1,3-dimethylbutyl)-N'-phenyl-phenylquinone) in surface water, groundwater, and domestic drinking water. This standard is a newly developed one. Based on the characteristics of 6PPD-quinone in water bodies and combined with the current situation of instrumentation and equipment in China and the requirements of the standard, this study uses an online solid-phase extraction system to pre-process 6PPD-quinone in water samples and combines it with a liquid chromatography-tandem mass spectrometer for detection, promoting a time-saving, labor-saving, and effective analysis method, and providing technical support for the analysis of 6PPD-quinone in water. The main technical content of this standard includes the study of sample collection and storage conditions, the optimization of pre-processing conditions of the online solid-phase extraction system, and the optimization of the liquid chromatography-tandem mass spectrometer conditions, as well as the verification of the detection limit, precision, and accuracy of the method.
