This document discusses different types of partition chromatography techniques. It begins by explaining that partition chromatography uses a thin film of a stationary liquid phase on a solid support, and separation occurs based on how compounds partition between the mobile and stationary phases. It then discusses liquid-liquid chromatography where both phases are liquid, and gas-liquid chromatography. The document provides examples of techniques like reversed phase chromatography, paper chromatography, and considerations for selecting a mobile phase. It also summarizes techniques including gel permeation chromatography, ion exchange chromatography, and affinity chromatography.
