COSMOSIL Cholester Columns

COSMOSIL Cholester is a reversed phase HPLC column with cholesteryl groups bonded silica packing material, which provides equivalent hydrophobicity like traditional alkyl group bonded silica packing materials (C₁₈, C₃₀). However, Cholester offers strong molecular shape selectivity for hydrophobic compounds to yield unique and reproducible separation patterns following the same analytical conditions used with other ODS columns.
