Product information

 

IC SI-90 4E (+ guard IC SI-90G)
IC SI-50 4E (+ guard IC SI-50G)
IC SI-52 4E (+ guard IC SI-92G)

  • Suitable for anion suppressor methods with sodium carbonate eluent

  • Suitable for the quantitative analysis of fluoride ion

  • SI-50 4E separates target inorganic anions from organic acids

  • SI-52 4E provides simultaneous analysis of oxyhalides and general inorganic ions

  • Carbonate peak does not interfere with analysis

  • Equivalent columns for Metrohm Metrosep A Supp 4, Metrosep A Supp 5, Metrosep A Supp 7 and Thermo Fisher Dionex IonPac AS14, IonPac As22, IonPac As23

IC SI-35 4D (+ guard IC SI-95G)

IC SI-35 2B (+ guard IC SI-2GF)

  • Columns for rapid analysis with suppressor method with sodium carbonate eluent

  • SI-35 4D provides rapid analysis of oxyhalides and general inorganic ions
