This document explores the methodologies and considerations for scaling up liquid chromatography (LC) processes from analytical to preparative scales. It provides detailed equations and practical guidance for optimizing parameters such as flow rates, injection volumes, and gradient times while maintaining efficiency and resolution. The paper also includes case studies demonstrating the purification of proteins like α-lactalbumin from milk fractions, highlighting variations in purity across different fractions. With a focus on achieving high reproducibility and maximizing yield, this guide serves as a valuable resource for researchers and industry professionals engaged in preparative chromatography.
