High Performance Liquid Chromatography (HPLC) Method for Analysis of Ivermectin and Doxycycline

vIvermectin is an anti-parasitic drug that is often used to treat or prevent parasites in animals and humans. Ivermectin and Doxycycline can be retained and separated on the Primesep 100 mixed-mode column using an isocratic analytical method with a simple mobile phase of water, acetonitrile (MeCN, ACN), and sulphuric acid (H2SO4) buffer. The analysis method can be UV detected at 250 nm.

Separation of Ivermectin B1b on Newcrom R1 HPLC column

February 16, 2018
Separation of Ivermectin B1b on Newcrom C18 HPLC column

Ivermectin B1b 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.
