HPLC Column, UDA (wcx), 4um, 2.1mm ID x 100mm Length, 100A. Cogent TYPE-C Brand. 1 EA.
Additional Info:
This Cogent UDA™ (wcx) HPLC Column is made with Cogent TYPE-C™ Silica, and has an 11 carbon chain with a terminal carboxylic acid group. This silica hydride based stationary phase provides excellent Selectivity, Faster Equilibration and Extremely Robust Column Lifetimes.
Use in Reversed Phase (RP), HILIC or as a Weak Cation Exchange Column (wcx at pH 6 or higher).
The hydrophobic stationary phase has direct silicon-carbon bonds which makes the column very robust and can be used for hydrophilic or hydrophobic compounds, if desired. Also can be used at very low pH (below 2) without damage.
This column is very popular and often chosen for LC-MS when increased resolution is desired.
The 40031‑05P‑3 Cogent UDA™ TYPE‑C™ HPLC column is a 100 mm × 2.1 mm ID analytical column packed with 4 µm, 100 Å TYPE‑C silica featuring a weak cation exchange (WCX) Undecenoic Acid (UDA) stationary phase, designed for balanced‑resolution LC‑MS separations of basic and positively charged compounds using mixed‑mode ion‑exchange and reversed‑phase mechanisms.
