# Determination of Bisphenol S (BPS) in the laboratory

## Your needs: measure the Bisphenol S in your materials

### What is Bisphenol S?

Bisphenol S is an organic chemical compound used in polymer matrices. It is found in epoxy resins, polycarbonate, polyethersulfone, thermal papers, phenolic resins and polyester resins. In general, the use of Bisphenol S is coupled with that of Bisphenol F but especially Bisphenol A, classified as a substance of concern.

The toxicity of Bisphenol S is equivalent to that of Bisphenol A (BPA). It must therefore be measured in a laboratory.

## Our solutions: Bisphenol S determination service

### Dosing techniques

Following the regulatory changes, FILAB laboratory has been able to set up specific methods for the determination of Bisphenol S by [HPLC-UV](https://filab.fr/en/our-technical-resources/laboratory-analysis-uplc/laboratory-analysis-hplc-lcms.md):
