3 Method summary
DBP, BBP, DEHP, DNOP in the sample in a Soxhlet extractor or solvent extractor with dichloromethane
DINP and DIDP 6 kinds of phthalate plasticizers were extracted, and the extract was fixed to volume and then liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/
MS) determination, external standard method for quantification.
