HPLC Column, NP Diol, 3um, 4.0mm ID x 100mm Length, 100A. Cogent Brand. 1 EA. CUSTOM ORDER.
This Cogent NP Diol™ Stationary Phase has been a premium value and used by HPLC laboratories for many years. Non end-capped, it is manufactured with the highest purity Silica available and bonded with a short hydrocarbon ligand that has a terminal, Diol Functional group. This make this Column ideal as an Alternate in any USP Method that uses the L20 Classification or for new methods.
With a 3µm Particle, this column is more efficient than a 5um column of the same phase and you will experience sharper peaks. However, due to the smaller particle size, there is an increased back pressure. It is often chosen to replace unmodified Silica columns in established methods, even though there may be slightly different selectivity because it can be more robust and more compatible with a wider range of solvents.
Use for hydrophilic or polar compounds in HILIC or Normal Phase HPLC.This is a CUSTOM ORDER manufactured item which cannot be returned or canceled once an order has been placed. Click HERE for more information on what is a Custom Order.
