SUPELCOSIL™ LC-Diol HPLC Column
5 μm particle size, L × I.D. 25 cm × 3.0 mm
 
SUPELCOSIL™ HPLC Columns
Traditional HPLC columns, similar to Hypersil™
Our SUPELCOSIL silica-based HPLC column line includes over 40 bonded phase chemistries, in a range of particle sizes and column configurations from microbore to preparative scale. It is the original high quality Supelco product line referenced in many USP methods.
In the case of a few SUPLECOSIL phases, we have recommended alternatives based on more advanced column technology.

LC-Diol
Suitable for L20 per USP
LC-Diol columns can be used to separate proteins by gel filtration chromatography; when operated with an aqueous buffer, the diol phase shields the silica surface from interacting with proteins. The separation of steroids and sterols is commonly done using a diol column under normal phase conditions.
