"SN/T 3114-2012 Determination of six phthalic acid esters in adhesives, inks, and Coating formulations, GC-MS method" stipulates the use of gas chromatograph-mass spectrometry to determine the content of six phthalic acid esters (DEHP, DBP, BBP, DINP, DNOP, DIDP) in adhesives, inks, and Coating formulations. The standard applies to the determination of samples after ultrasonic extraction, using n-hexane as the extraction solvent, after qualitative filter paper and membrane treatment. Quantification by internal standard method to ensure the accuracy and Reliability of the determination results. This standard describes in detail the steps of Sample Handling, Instrumentation and Data analysis, providing an effective method for assessing phthalic acid ester content in products.
