SunBridge
SunBridge columns from ChromaNik are based on a hybrid silica gel with ethylene bridges in the silica backbone. SunBridge C18 is modified with a trifunctional C18 ligand and then subjected to a complex endcapping process. First, a double endcapping is carried out with TMS and the bidentate 1,2-bis(cholorodimethylsilane). The remaining silanol groups are then converted to siloxane groups at higher temperatures, resulting in a highly endcapped phase.
