HPLC Method for Separation of Ketoconazole and Potassium Sorbate on Primesep B Column
February 7, 2023
HPLC Method for Separation of Ketoconazole and Potassium Sorbate on Primesep B by SIELC Technologies
Ketoconazole, also known as Nizoral, is an antifungal compound with the chemical formula C26H28Cl2N4O4. It is used to treat dandruff and is commonly available as a shampoo. It is applied to skin to treat other fungal infections. Ketoconazole also has antiandrogen and antiglucocorticoid properties. It works through interfering with the fungal synthesis of ergosterol and other enzymes. You can find detailed UV spectra of Ketoconazole and information about its various lambda maxima by visiting the following link.
Potassium Sorbate is a popular preservative with the chemical formula C6H7KO2. It is used in a wide variety of foods, wines, and personal-care products. It works through inhibiting molds, yeasts, and various other microbes. You can find detailed UV spectra of Potassium Sorbate and information about its various lambda maxima by visiting the following link.
Potassium sorbate, Sodium sorbate, Ketoconazole can be retained, analyzed, and separated on a Primesep B reverse-phase column using a gradient analytical method with a mobile phase consisting of Acetonitrile (MeCN), water, and Sulfuric acid as the ionic modifier. This analysis method can be UV detected at 200 nm with high resolution and peak symmetry.

Separation of Sodium sorbate on Newcrom R1 HPLC column
May 16, 2018
Sodium sorbate 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.
