TYPE-C™ silica based HPLC columns have opened a new chapter in the book that describes chromatographic supports and phases. Based on high purity-low metal content Type-B silica, the manufacturing process for TYPE-C Silica™ continues where others leave off. Our process produces a surface populated with silicon-hydride groups (Si-H) which are very stable and non polar.

The TYPE-C Silica™ support still has all the advantages of Type-B silica such as spherical shape, low metal content, high purity, high mechanical strength, narrow pore size distribution, wide range of pore sizes, easily chemically modified, no swelling in the presence of solvents for stable packed beds and does not produce fines as irregular silica. TYPE-C Silica™ products also have many advantages over the ordinary Type-B columns on the market.

Among them is that they can be used for 3 different modes of HPLC and sometimes two at the same time. This gives you an enormous selectivity power. On one column you can separate polar and non polar compounds at the same time or in different runs. One column can be used for classic reverse phase, normal phase with non polar solvents such as hexane and can be used for normal phase elution with aqueous solvents. This is called Aqueous Normal Phase.

Other benefits are the incredible speed between gradient runs that can be used to equilibrate or clean your column from matrix effects. For normal runs, less than one minute is needed.
