Water analysis service providers and industrials measure various indexes on samples prepared by AGLAE. These analyses correspond to the monitoring of water intended for human consumption, surface water and the monitoring of wastewater treatment plant discharges. 
⇒ AGLAE offers 4 programmes in this category of interlaboratory tests Indexes in waters.
AGLAE estimates the analytical performance of participants, enabling them to improve the quality of their analyses.

Why take part in "indexes in waters" proficiency tests?


Contenu

They are carried out as part of self-monitoring or regulatory controls. They enable part of the requirements to be covered:

  • accreditation scopes related to physico-chemical analyses in waters (see Accreditation No. 1-1664) 
  • approvals issued by Ministries of Health to carry out sampling and analysis for water quality control purposes 
  • approvals issued by Ministries for the Environment to carry out analyses in the field of water and aquatic environments

Added value of AGLAE "Indexes in waters" proficiency tests


Contenu

Depending on the methods used to analyse the indexes, differences in results are observed. AGLAE studies them and presents them in the test reports. These observations help laboratories to better interpret their analysis results.
AGLAE has published a study on indexes resulting from tests observations: Anionic surfactant index, comparison of global analysis methods (spectrophotometry with or without flux).
AGLAE's proficiency tests are used not only to assess laboratory performance, but also to check their estimated measurement uncertainties and to assess the repeatability and reproducibility of their measurements.
AGLAE provides personalised reports to laboratories, enabling them to focus on possible improvements to their analyses.
