HPLC Columns Based on TYPE-C Silica-Hydride Unbonded
Since these columns have virtually no silanols remaining (less than 3%), they do not have a strong association with water and other solvents. This allows you to use these columns for normal phase HPLC without having to concern yourself with the moisture content of the solvents. Typically, this can be a very tedious and costly procedure which is now eliminated with Cogent Silica-C. These columns are an excellent choice for normal phase and preparative chromatography for the above reason and because they produce a very unique selectivity and retention ability. Also, these columns, even though they are carbon free, can be used to retain some polar compounds in Aqueous Normal Phase making it a favorite of many doing LCMS.
