Determination of PFASs in Food Contact Material by LCMS-8050

User Benefits

- Compared with the original standard, the number of PFCs tested was increased to 17, which improved the applicability of the method. - Run time of 15 minutes while ensuring good chromatographic separation and peak shape.

Introduction

Due to the unique physical and chemical properties of per- and polyfluoroalkyl substances (PFASs), such as reducing surface tension, good stability, hydrophobicity, and hydrophilic, so it is very widely used in the field of food contact materials. It is mainly used for the production of plastic film, PVC food packaging, waterproof, and oil-proof coating on the surface of food packaging (such as waterproof oil paper products) and non-stick cooker coating, etc. Research has shown that PFASs will migrate from food contact materials to food, and then contaminate the food that comes into contact with it, entering the human body. PFASs are very stable, difficult to be metabolized and biodegraded in the body, and exhibit the characteristics of persistence, accumulation, and long-distance migration. It can be accumulated and amplified in the food chain and enriched in the organisms, endangering human health. Refer to the sample preparation method in GB 31604.35-2016, determination of both Perfluorooctane Sulfonates (PFOS) and Perfluorooctanoic Acid (PFOA), an analytical method for the determination of 17 perfluorinated compounds in food contact materials was built.
