Applications:


Effect of Acid on Separation of Xanthines



Primesep B separates xanthines such as theobromine, dimethylxanthine, theophylline by a combination of reversed-phase and ion-exchange mechanisms. The anion-exchange properties of the column allow retention of hydrophilic xanthines, and the reversed-phase properties retain hydrophobic compounds. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and either trifluoroacetic acid (TFA), perchloric acid (HClO4), or sulfuric acid (H2SO4) and UV detection.



Application Analytes:

Theophylline
Theophylline monohydrate

Separation of Theophylline monohydrate on Newcrom R1 HPLC column

Theophylline monohydrate 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.
