HPLC columns, Cogent Bidentate C18™

HPLC columns, Cogent Bidentate C18™

Using proprietary bonding technology, the straight chain C18 hydrocarbon is bonded directly to the TYPE-C silica-hydride surface at two separate points of attachment with direct siliconcarbon bonds. This Si-C bond is virtually indestructible and confers great stability and longevity to these columns.

Suitable for use with mobile phases containing from 100% water to 100% organic solvent
Very hydrophobic phase
Columns operate in RP, ONP, and ANP
Easy gradient analysis

These columns are ideal for generic or USP methods which specify the use of a C18 (or USP L1) column.
