Campden BRI awarded UKAS accreditation for quaternary ammonium compounds (QACs) testing
Campden BRI has been awarded UKAS accreditation for the testing of benzalkonium (BAC) and didecyldimethylammonium chloride (DDAC). BAC and DDAC are widely used in disinfectants and sanitisers due to their effective biocide properties.
The maximum residue levels (MRLs) of QACs used for disinfectant purposes was reduced to 0.1mg/kg in all foods from 0.5mg/kg by the European Commission in August this year. This has prompted the need for improved analytical methods.
Julian South, Head of Chemistry and Biochemistry said: "We can test for BAC and DDAC in all food products using sophisticated mass spectrometry which has a detection limit of 0.01 mg/kg. As well as testing food, we can also work with companies to help them reduce QAC levels in their food products or trial alternative disinfection substances."
Campden BRI now has UKAS accreditation for 93 tests. You can find a full list of Campden BRI's UKAS accredited methods on the UKAS website.
