HPLC Determination of 2-Phosphonobutane-1,2,4-tricarboxylic on Newcrom BH Column
January 18, 2021
PBTC (2-phosphonobutane-1,2,4-tricarboxylic acid) is one of the most widely used scale inhibitors in the cooling water treatment industry. PBTC 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, 2-phosphonobutane-1,2,4-tricarboxylic acid can be retained and UV detected at 220nm.

Application Column
Newcrom BH
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.

Separation of 2-Phosphono-1,2,4-butanetricarboxylic acid on Newcrom R1 HPLC column
February 16, 2018
2-Phosphono-1,2,4-butanetricarboxylic acid can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.
