HPLC Column, UDC Cholesterol, 4um, 4.6mm ID x 250mm Length, 100A. Cogent TYPE-C Brand. 1 EA.
Additional Info:
This UDC Cholesterol™ HPLC is made with Cogent TYPE-C™ Silica, and provides unique Selectivity due to different surface chemistry, compared to typical Reversed Phase Columns. This Silica Hydride Phase is modified with an 11 carbon chain with a cholesterol molecule attached at the terminus. This gives this column the ability to form “slots” and separate some compounds based on shape. Also, due to the direct silicon carbon bonds, this column has no need for end-capping. Use in Reversed Phase, Normal Phase and Aqueous Normal Phase (ANP).
Chosen for analyzing steroidal and other hard to retain compounds including some lipids, peptides, proteins & oligonucleotides.
Faster Equilibration than other Reversed Phase or HILIC Columns
Very Hydrophobic
Robust Column Lifetimes
Temperature and Solvent Changes Selectivity
Chosen when more separation between closely related compounds or longer retention times is needed.
