Phenols in groundwater

P2537-RT is designed to cover the quantification of a selection of phenols in groundwater matrix by GCMS or similar methods. The selection of analytes is based on the German method DIN 38407-27:2012-10 (F27).

Groundwater from a groundwater measuring point is chosen as a matrix and spiked with the phenols listed below. LOQs of 0.5 µg/l are required for the individual phenols.

The aim of this ring test is the correct quantification with respect to

the comparability criterion (z-score)
the trueness criterion (70 - 120 % recovery of the spiked level)

This ring test is not included in the scope of our accreditation yet. Independent from our scope of accreditation, all ring tests are organised and performed in accordance with the requirements of DIN EN ISO/IEC 17043:2023.
