Ion Chromatography Standards
Ion chromatography (IC) separates charged molecules based on their affinity to the ion-exchange resin. It is of two types- cation exchange and anion exchange. IC determines the ions in aqueous solutions down to the parts per trillion (ppt) range. It is one of the best methods to offer quantitative analysis of ions at the ppt level. The development of modern apparatus and columns has made IC a fast, uncomplicated, and reliable tool for analysis.
The calibration and quality control of an IC system is of vital importance and requires the selection of appropriate standards. We offer a wide range of reference materials for IC, starting from single-ion standards to multi-ion standards. These standards are frequently used by the environmental, food and beverage, pharmaceutical, and other industries.
Our portfolio consists of CRMs from the well-known Certipur® and TraceCERT® brands. These certified reference materials are produced under ISO/IEC 17025 and ISO 17034 double accreditation. The CRMs are traceable to standard reference materials (SRM) from the National Institute of Standards and Technology (NIST).
