Diluted, Certified Standard Solutions (CRM) for Water and Wastewater Analysis

No Dilution. No Doubts. No Delays. Just Precision.

Our new certified standard solutions (CRMs) are perfect for quality control for photometric methods, standards and our Spectroquant® Test Kits. We also offer ready-to-use standards for TOC analyzers, ICP-OES or Ion chromatography. To ensure accurate results, our CRMs can also be used as standards for test kits from other suppliers.

Our CRMs are directly traceable to NIST primary reference materials, and offer an expanded measurement uncertainty for every concentration. Whether you are analyzing drinking water, process water or wastewater, you’ll have no doubts, no dilution, and no delays. Just open a bottle of our certified reference materials and experience the highest standard in precision.
