HPLC Application of Simultaneous Separation of Cations and Anions  Primesep 100 and Primesep B columns connected in series allow the quantitation of sodium chloride and potassium bromide ions in one injection. The Primesep B column retains the chloride and bromide anions by anion exchange, and the Primesep 100 retains the sodium and potassium captions by cation exchange. The separation uses a mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) with evaporative light scattering detection (ELSD). Application Analytes: Bromide Chloride Potassium Sodium Application Detection: ELSD/MS Detection |
