HPLC Column, UDC Cholesterol, 4um, 3.0mm ID x 150mm Length, 100A. Cogent TYPE-C Brand. 1 EA.

CUSTOM ORDER.

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

This size column provides similar run times as a 4.6mm ID column, but uses much less mobile phase, with lower flow rates. No special equipment is needed for this column to save solvent use.
