Description
Separating atorvastatin-related substances using a Zodiac Phenyl column involves a specific approach in high-performance liquid chromatography (HPLC). Developing an HPLC method using a Zodiac Phenyl column for separating atorvastatin-related substances involves optimizing the mobile phase composition, gradient elution, and detection conditions to achieve accurate and reproducible results. Method development and validation are crucial steps to ensure the method is suitable for routine analysis in pharmaceutical quality control, adhering to USP guidelines and regulatory requirements.
