C18-Alkaline C18 Chromatography Analytical HPLC Columns ...
The C18-Alkaline HPLC Columns packed by hydrophilic functional groups bonded silica (high purity) so as to realize hydrophilic features. Hydrophilic groups are embedding into the ultra-pure silica to make it Hydrophilic. Hydrophilic groups replace most of the silanol groups to prevent the reaction between the basic compounds and silanol groups.

What Is C18? A Guide on the Basics of HPLC …
Nov 06, 2019 · C18, C8, and C4 are all linear alkylsilane phases. C18 is octyldecylsilane and contains 18 carbons bound to the silica. So they have more carbons and a longer carbon chain than C8 (8 carbons) or C4 (4 carbons). Because of the extra carbons, C18 has a larger surface area that the mobile phase has to travel across.Estimated Reading Time: 6 mins
