Application Column
Newcrom B
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.

HPLC Separation of Coumaric acids on Newcrom BH Column
January 27, 2021
p-Coumaric acid is the major phenolic acid in a wide variety of graminaceous plants. p-Coumaric acid is a natural metabolite contained in many edible plants and its antioxidant activities in reducing oxidative stress and inflammatory reactions have been demonstrated in various experiments The three isomers of coumaric acid can be detected at low UV. Using Newcrom BH mixed-mode column and a mobile phase consisting of acetonitrile (ACN), and water with phosphoric acid (H3PO4) buffer, the acids can be retained and UV detected at 270nm.
