Diol Gravity

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 Gravity Chromatography Columns

Diol Gravity is available in porosities of 100Å, 300Å, and 500Å and a particle size distribution of 75-200µm.

Quality and diversity

Diol Gravity is manufactured on Sorbtech’s Premium Rf^TM 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 (99.9% 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.
