3 Principle

The sample is extracted with methanol as a solvent, and after being extracted by an ultrasonic water bath, the membrane is cooled to be a liquid to be tested, and an appropriate amount of the liquid to be tested is used for ultra performance liquid chromatography. The tandem mass spectrometry (UHPLC-MS/MS) was used for analysis, and the content of perfluorooctanoic acid or perfluorooctane sulfonic acid in the sample was quantitatively calculated by an external standard method.
