AN73053: Assay of Potassium Bitartrate using Ion Chromatography Be the first to rate this application


We developed an ion chromatography (IC) method to replace the titrimetric assay for potassium bitartrate in the United States Pharmacopeia (USP) Potassium Bitartrate monograph. Our IC method offers a significant improvement to the existing assay inthe USP monograph. It is a 5 min method that uses a Dionex™ IonPac™ AS20 ion-exchange column, an electrolytically generated KOH eluent, and suppressed conductivity detection on a Thermo Scientific™ Dionex™ Reagent-Free™ Ion Chromatography (RFIC™) system supported by regulatory compliant Chromeleon™ Chromatography Data System (CDS) software.
