HPLC Method for Determination of Flunixin and Meglumine on Primesep 100 Column
September 27, 2022
HPLC Method for Determination of Flunixin and Meglumine on Primesep 100
Separation type: Liquid Chromatography Mixed-mode
Flunixin is an analgesic and antypyretic nonsteroidal anti-inflammatory drug (NSAID) typically used by veterinarians in bovine and equine treatments. It is typically produced as a Meglumine salt, which helps stabilize and bulk up the medication in its solid form. Flunixin and Meglumine can be retained, separated, and analyzed on a Primesep 100 mixed-mode stationary phase column using an isocratic analytical method with a simple isocratic mobile phase of water, Acetonitrile (MeCN), and a sulfuric acid (H2SO4) buffer. This analysis method can be UV detected at 252 nm (Flunixin) with high resolution and peak symmetry and is compatible with Mass Spectrometry (MS), ELSD, and CAD (Flunixin and Melumine).

Separation of Flunixin meglumine on Newcrom R1 HPLC column
February 16, 2018
Flunixin meglumine 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.
Application Column
Newcrom R1
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.
