Dairy Chemistry (QDCS)

daps UKAS Logo
  • UKAS accredited proficiency testing scheme
  • The LGC Quality in Dairy Chemistry Scheme (QDCS) is a comprehensive proficiency testing scheme available to laboratories performing compositional and safety analysis in the dairy sector.
  • Laboratories may test dairy products to ensure a commercial product performs within preset quality standards, or to look for adulterations or contaminants that could adversely affect a product.
  • For laboratories that perform the analysis of dairy products using traditional ‘wet’ chemistry techniques, as well as determinations by infrared analysers and other methods, participation in a relevant LGC Proficiency Testing scheme can provide confidence that results are meaningful and accurate which, in turn, helps to ensure the safety of dairy foodstuffs.
  • Scheme operates from January to December
