Hiden Analytical announces that the nitrogen excess (N₂/Ar) groundwater analysis method operated by Aqua Service Schwerin (AQS Schwerin) has achieved DAkkS accreditation using the HPR-40 MIMS (Membrane Inlet Mass Spectrometer) supplied by Hiden. As part of its DAkkS-accredited scope,AQS Schwerinperforms N₂/Ar measurements on groundwater with the HPR-40 MIMS system designed and manufactured by Hiden. This accreditation demonstrates that Hiden’s MIMS-based workflow is suitable for routine, regulator-recognised groundwater monitoring in Germany—supporting water management, environmental protection, and compliance-driven reporting. Regulatory validation and market relevanceThe accreditation comes at a time of increasing regulatory requirements for groundwater and raw water monitoring in Germany. New regulatory frameworks and raw water protection regulations require comprehensive self-monitoring by water utilities and operators, including advanced analytical methods such as nitrogen excess (N₂/Ar) analysis. This significantly increases demand for reliable measurement technologies capable of delivering high-precision data for:groundwater protection programsnitrate and nitrite risk assessmentevaluation of denitrification processesearly risk detection for drinking water supplyregulatory reporting and complianceBy integrating Hiden Analytical systems into an officially accredited DAkkS measurement scope, this development establishes MIMS-based analysis as atrusted solution for operational groundwater monitoring. Technology behind the accreditationTheHPR-40 MIMSenables continuous, in-situ measurement of dissolved gases such asN₂, Ar, O₂, CO₂, CH₄and N₂Odirectly in water. This allows real-time assessment of denitrification processes under real environmental conditions, deliveringhigh accuracy, strong reproducibility and reliable long-term performancecompared to conventional laboratory-based methods. Strategic importance for the marketThis accreditation represents a key milestone for the adoption ofHiden Analyticalmass spectrometry systems in groundwater monitoring across Germany and Europe. It demonstrates that Hiden systems are not only research instruments, butregulatorily recognised analytical solutionssuitable for official monitoring programs, water utilities, environmental authorities and accredited laboratories. Peter Hatton, Director at Hiden Analytical, commented“The inclusion of Hiden Analytical’s HPR-40 MIMS system within a DAkkS-accredited analytical scope marks a decisive step toward establishing mass spectrometry-based N₂/Ar analysis as a standard tool for groundwater protection and regulatory monitoring. ”
