COSMOSIL 3Cholester 3 µm HPLC Columns

Specialty for Structual Isomers / Hydrophobic interaction and planarity selectivity

COSMOSIL Cholester is a new silica based RP column which employs a cholestery bonded phase. Cholester provides enhanced selectivity over traditional C18 materials and greater performance in separating isomers or other closely related compounds. Cholester is ideal for method development and serves as an excellent alternative to traditional C18 columns.
