Proficiency Tests

Proficiency Tests are based on the principle that many laboratories provide  results on a sample that the value is not known by the laboratories, and all results are compared with the reference value by the organizer body after delivery.

EN ISO/IEC 17043 standard defines general requirements for proficiency tests and providers. This standard is used as a base for accreditation of Proficiency Test Providers.

c Some of the potential benefits for participating laboratories of proficiency testing are;

  • Confirming competent performance
  • Identifying testing or measurement problems
  • Comparing methods and procedures
  • Improving performance
  • Educating staff
  • Instilling confidence in staff, management and external users of laboratory services
  • Comparing operator capabilities
  • Generating reference materials
  • Determining method precision and accuracy
  • Satisfying regulators and accreditation bodies
  • Providing laboratories with additional risk management

New proficiency testing schemes – perfluorinated compounds (PFAS)

Our new proficiency test program “PFAS” offers you perfectly tailored proficiency tests in various foodstuffs and consumer goods.

The concentration levels are always adapted to the respective matrix (ng/kg, µg/kg, mg/kg), the following PFAS are requested:

– CAS 1763-23-1 (perfluorooctanesulfonic acid)

– CAS 335-67-1 (perfluorooctanoic acid),

– CAS 375-95-1 (perfluorononanoic acid),

– CAS 355-46-4 (perfluorohexanesulfonic acid)

Many new proficiency testing schemes are already being planned and will be published in the course of the year.

We will keep you up to date on this with our announcements.

New proficiency testing schemes – pesticides

Our new proficiency testing program “Pesticides” was developed with leading experts in the field of pesticide analysis.

The sample design considers the measurement of blank samples and covers different concentration ranges.

All relevant matrix groups according to SANTE 11312/2021 are represented.
