COSMOSIL 2.5Cholester 130Å - 2.5µm

COSMOSIL Cholester is a reversed phase HPLC column with Cholesteryl bonded silica packing material, which provides equivalent hydrophobicity like that of traditional ODS columns. However, Cholester offers strong stereoselectivity for hydrophobic compounds to yield unique and reproducible separation patterns following the same analytical conditions used with other ODS columns.

Cholesteryl bonded groups are very rigid structures and offer improved separation of compounds that are difficult to analyze with Alkyl Group bonded materials.
