preparative-scale liquid chromatography

Preparative-scale liquid chromatography (LC) is a technique used for separating and purifying substances, particularly organic compounds. It involves a stationary phase (often a solid packed into a column) and a mobile phase (a liquid) that flows through it. A sample is introduced, and its components separate based on their differing affinities for the stationary and mobile phases. Substances that interact more strongly with the stationary phase move slower, allowing for their separation from others.

This method is versatile, capable of separating a wide range of compounds, including inorganic ions, amino acids, drugs, and proteins. Preparative-scale LC is crucial in biotechnology for purifying large quantities of substances like proteins and peptide hormones. The separated components can be collected for further use.12
