"SN/T 4573-2016 Determination of diethylene glycol dimethyl ether in Coatings, inks, Adhesive, Gas chromatograph - Mass spectrometry" specifies the method for the determination of diethylene glycol dimethyl ether in water-based paints, solvent-based paints, inks and Adhesive. This method uses gas chromatograph Mass Spectrometry (MS), extracts the sample by dilute solvent, and the extract is purified by a microporous filter membrane and then tested by GC-MS. The reagents used in this standard are all analytically pure, including the use of diethylene glycol dimethyl ether reference materials and internal standards to ensure the accuracy and Reliability of the test. The standard also describes in detail the preparation methods of standard and working solutions, as well as the necessary instrumentation and equipment requirements, such as Balance, vortex mixer, and Centrifuge, to support experimental operations during analysis.
