Ion chromatography (IC) is an analytical process for the separation of ions based on charge affinity. IC can be used for a variety of different kinds of charged analytes from single elements to large proteins. In order to ensure accurate analysis, quality standards which are traceable and stable are necessary. SPEX CertiPrep offers the highest quality IC standards available for the analytical laboratory.
