Do you need control materials to validate your methods or carry out your quality control?

In addition to organizing proficiency testing schemes, we provide you with leftover samples from proficiency testing rounds in the agri-food and environmental fields. These are available for laboratories that wish to develop internal quality controls with safe samples. All of them come with a certificate that includes:

  • Assigned value and associated uncertainty, and the number of laboratories assigning it
  • Details about the nature of the sample, representative of the matrices commonly analyzed
