Diol HPLC Analytical
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 the 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 HPLC, UHPLC, SFC, or Capillary LC
Diol HPLC Analytical is available in porosities of 100Å, 150Å, 200Å, and 300Å and particle sizes of 2µm, 3µm, 5µm, and 10µm.
Quality and diversity
Diol 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, 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.
