WEPAL/QUASIMEME Proficiency Testing

WEPAL-QUASIMEME Proficiency Tests


Wageningen Research has advanced facilities for ring testing and reference materials, housed in WEPAL-QUASIMEME. These studies form the basis of external quality assurance for institutes that regularly perform chemical measurements in the terrestrial, aquatic and/or marine environment. Several accredited ring testing programmes are offered to laboratories worldwide. Each of the programmes covers a wide range of determinants. For more information about the individual programmes select a programme in the left menu bar.

WEPAL-QUASIMEME has built up experience in organising proficiency tests since the early 1950's and has been accredited for organising interlaboratory tests according to ISO-17043 since 2000. The organisation also complies with ISO-9000 and ISO-14001. Participants can use the results of proficiency tests for:

  • validation of internal laboratory quality assurance
  • improvement of methodology
  • support of accreditation
  • support of quality assurance for environmental monitoring data
  • providing data for national or international programmes.

WEPAL-QUASIMEME also supplies samples from the ring research programmes as reference material. These can be used for method development or as reference samples for internal quality control.

Furthermore, WEPAL-QUASIMEME offers development rounds for e.g. new pollutants or problems with the analytical methodology, and workshops for discussion and improvement of the methodology. WEPAL-QUASIMEME is interactive, participants can always ask for specific determinants and matrices to be included in the program and suggest development rounds and workshop topics for e.g. new pollutants.
