GromSil 100 SAX is a strong anion exchange (SAX) column from Dr. Maisch HPLC GmbH, based on fully porous, high-purity silica with a 100 Å pore size and functionalized with quaternary ammonium groups. This phase offers strong electrostatic retention for negatively charged compounds such as organic acids, nucleotides, and other anionic analytes.
Its stable performance and robust ion-exchange capacity make it ideal for both analytical and preparative applications using salt gradients or isocratic conditions.
Engineered for selective retention of acidic analytes, this SAX phase from Dr. Maisch HPLC GmbH ensures reliable separation performance — ideal for ion-exchange methods in quality control and research environments.
