Phenomenex Star-Ion™ A300 - 100/4.6

Phenomenex Star-Ion™ A300 - 100/4.6
Beställningsnummer: 6.1005.100

The Star-Ion A300™ - 100/4.6 IC anion column's separation properties are based on the use of styrene-divinylbenzene resin. The separation between the "water dip" and chloride is not as sharp as with acrylate-based and vinyl alcohol-based columns. The Star-Ion A300™ - 100/4.6 exhibits lower separating efficiency in the fluoride range. This column nevertheless impresses with its extremely short analysis times.

The system peak and high carbonate concentrations interfere with the integration of the chloride peak. It is therefore recommended that the "MCS" (Metrohm CO2 Suppressor) be used.

  • Metrosep RP 2 Guard/3.5
    Metrosep RP 2 Guard/3.5
    General guard column. For Metrosep Anion Dual 2 and Dual 3 in particular.
  • Metrosep RP 3 Guard HC/4.0
    Metrosep RP 3 Guard HC/4.0

    The Metrosep RP 3 Guard HC/4.0 is a guard column for universal use. It reliably protects the analytical separation column against contamination, securely removing lipophilic organic contamination, the smallest particles, traces of iron oxide and bacteria. The guard column is based on a polymer material and thanks to its larger pack volume, has a significantly higher capacity that the Metrosep RP 2Guard/3.5. It can be used in the entire pH range.
