Diol HPLC Semi-Prep

Diol Silica can be used in both the Normal Phase and Reversed Phase modes, just as Amine and Cyano bonded phases.  Diol Silica is much less chemically reactive as compared to Amine Silica.  It is also insensitive to water content of mobile phases.  It can be washed with water without causing difficulties. 

Diol bonded phases are particularly useful for aqueous GPC applications. 

Recommended Applications:

  • Food additives from beverages
  • Alkaloids from plants
  • Antibiotics from ointments
  • Pesticides
  • Prostaglandins

For Semi-Prep HPLC and SFC

Diol HPLC Semi-Prep is available in porosities of 10, 300Å, and 500Å and particle sizes of 5µm10µm, and 15µm. 

Quality and diversity

Diol HPLC Semi-Prep is manufactured on Sorbtech’s Premium RfTM 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, ensures 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.
