Diluted, Ready-To-Use and in Varying Concentrations
Precise and accurate results are crucial – especially when analyzing water and waste water. Photometric rapid tests for in-process controls – as well with DIN, ISO, EN, APHA, EPA and USP – can be used to test the quality of water without hassle, but for reliable and reproducible results, the methods used must be checked regularly. When it comes to analytical quality control, standard solutions that are traceable to globally accepted primary standards are essential. We have developed certified, diluted standard solutions which are traceable to standard reference materials (SRM) from the National Institute of Standards and Technology (NIST) or to United States Pharmacopeia USP.
With standard solutions (CRM) from MilliporeSigma for photometric applications, for TOC analyzers, for ICP-OES and for Ion chromatography you can perform your internal analytical quality control reliably and without extra effort. Time-consuming dilution is no longer necessary, since our standard solutions are ready-to-use, certified and come in varying concentration. And most importantly: They provide users with the certainty that they are traceable directly to primary standard reference materials (SRM) from NIST or USP. This ensures that quality standards are comparable internationally.
