Interlaboratory comparisons

On request AQS Baden-Württemberg provides interlaboratory comparisons and bilateral proficiency test also for other customers. In principle the same requirements are valid as for the other PTs. Deviations may be possible due to low numbers of participants

Many times such interlaboratory comparisons have been organized for the Landesanstalt für Umwelt, Messungen und Naturschutz (LUBW) for the analysis of certain substances in ground water. The LUBW uses these interlaboratory comparisons as criteria for awarding contracts for the ground water monitoring network in Baden-Württemberg.

In most cases the evaluation is done according to DIN 38402 - A45 / ISO/TS 20612. Assessment is done according to the needs of the customer.

If you need such an interlaboratory comparison, please do not hesitate to contact us!
