SIELC is well-known for its high level of know-how in Chromatography and offers high quality columns. Primesep and Promix offer a wide range of normal and reverse phase columns in various lengths and diameters.
The technology of the SHARC columns (specific hydrogen-bond adsorption resolution column) is characterised by the predominant formation of hydrogen bonds, which focuses on the bonds to electronegative atoms. The columns from the SIELC Obelisc series have been designed for the separation of small molecules. The bonds here are based on the liquid separation cell technology (LiSC). Legacy columns are made of octadecylsilane bound to porous silica or ceramic particles which comply with the USP regulations.
