Exsil 100 HAAX is a high-activity anion-exchange HPLC stationary phase based on high-purity Exsil 100 silica with a nominal pore size of 100 Å. The strongly basic anion-exchange functionality provides high charge density and strong electrostatic interactions, enabling efficient retention and separation of negatively charged analytes.
The HAAX surface chemistry is designed for ion-exchange chromatography of small to medium molecular weight anionic compounds. The phase offers strong and reproducible retention, high loading capacity, and stable selectivity across a wide range of mobile phase conditions, making it suitable for both analytical separations and method development.
Controlled silica synthesis and robust surface modification ensure excellent batch-to-batch reproducibility, consistent chromatographic behavior, and reliable long-term performance.
Exsil 100 HAAX delivers strong anion-exchange selectivity, robust performance, and reliable reproducibility, making it a powerful tool for ion-exchange HPLC separations of negatively charged small molecules.
