This standard specifies the method for the determination of perfluorooctanoic acid (PFOA) and its salts in Coatings, using high performance liquid chromatograph-tandem mass spectrometry technology. The detection limit of the method is 0.0002% of the mass fraction of perfluorooctanoic acid. Analysis is carried out through water ultrasonic extraction, centrifugal separation and solid phase extraction column purification to ensure accurate determination of perfluorooctanoic acid and its salts in Coatings.
