WAX Silica HPLC Semi-Prep
WAX Silica is a weak anion exchanger. The bare silica is modified using Polyethylenimin (PEI) which includes several tertiary Amine Groups in the skeleton. The polymerization degree is about 30.
WAX Silica is suitable for the separation of strong basic compounds and has a strong ion exchange capacity.
For Semi-Prep HPLC and SFC
WAX Silica HPLC Semi-Prep is available in porosities of 100Å, 300Å, and 500Å and particle sizes of 5µm, 10µm, and 15µm.
Quality and Diversity
WAX Silica HPLC Semi-Prep is manufactured on Sorbtech’s Premium Rf™ Spherical Silica Gel which boasts narrow pore and particle distributions, ensuring optimal selectivity, capacity, efficiency, low operating pressure, and shorter processing time.
Purity
Premium Rf Spherical Silica Gel is manufactured to a high chemical purity standard (99.95% SiO2). Organics and trace metals content are controlled within stringent limits. Each production batch has undergone extensive quality control testing to ensure reliable lot-to-lot performance. This rigid control of chemical purity, surface area and pore size, ensure our silica will yield reproducible separation results and allow for direct scale-up without requiring time-consuming method redevelopment.
Robust
Our spherical silicas are mechanically robust and can, therefore, be repacked multiple times in either analytical or preparative scale columns.
