Lactic acid (milk acid) is a natural organic acid that plays an important role in biochemical processes. It has a carboxylic and hydroxy- groups which, upon standing, can react with each other and form dimers, trimers and higher oligomers. Lactic acid is a polar molecule that does not retain on reversed-phase columns. Newcrom BH mixed-mode anion-exchange column is used for the separation of lactic acid and its oligomers by a combination of weak reversed-phase and anion-exchange mechanisms. Lactates can be monitored by low UV, ELSD, CAD or LC/MS.

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.Select options
