Separation type: Liquid Chromatography Mixed-mode
Ketoconazole, also known as Nizoral, is an antifungal compound used to treat dandruff and is commonly available as a shampoo. Ketoconazole can be retained, analyzed, and separated from Potassium sorbate 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.
