WAX Silica HPLC Analytical
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 HPLC, UHPLC, SFC, or Capillary LC
WAX Silica HPLC Analytical is available in porosities of 100Å, 150Å, 200Å, and 300Å and particle sizes of 2µm, 3µm, 5µm, and 10µm.
Quality and Diversity
WAX Silica HPLC Analytical is manufactured on Sorbtech’s Premium Pure™ Spherical Silica Gel which boasts very narrow pore and particle distributions, ensuring optimal selectivity, capacity, efficiency, low operating pressure, shorter processing time; and are therefore, the best balance between high performance and value.
Purity
Premium Pure Spherical Silica Gel is manufactured to a very high chemical purity standard (>99.99% 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.
