3 Terms and definitions
There are no terms or definitions that require definition in this document.
4 Principle
The perfluorinated and polyfluorinated compounds in the sample were extracted with tert-butyl methyl ether by ultrasonic. The extract was concentrated and filtered through a microporous membrane.
Qualitative analysis was performed by GC-MS and quantitative analysis was performed by external standard method.
