GromSil Anion is a strong anion exchange (SAX) column from Dr. Maisch HPLC GmbH, designed for the efficient retention and separation of negatively charged analytes. Based on fully porous, high-purity silica and functionalized with quaternary ammonium groups, this phase enables strong electrostatic interaction with anionic species such as organic acids, nucleotides, and sulfate- or phosphate-containing compounds.
Its robust surface chemistry and high ion-exchange capacity make it suitable for use in pharmaceutical, environmental, and biochemical workflows employing aqueous buffer systems.
With strong retention of anionic compounds and excellent chemical stability, GromSil Anion from Dr. Maisch HPLC GmbH is a dependable solution for high-performance ion-exchange separations.
