Certipur® Certified Single-Element Standards for Ion Chromatography


Within its Certipur® range of certified reference materials, Merck offers a wide range of single-element standards especially designed for instrument calibration in ion-exchange chromatography (IC) applications, e.g. for environmental or food analysis and quality control.

Our Certipur® single-element standards for ion chromatography are available as both ready-to-use calibration solutions and concentrates. All our Certipur® IC standards – with the exception of fluoride – are traceable to primary standard reference materials from NIST. With Merck’s Certipur® CRMs for ion chromatography, you benefit from easy handling and precise, reliable analytical results.
