The laboratory technique used for the separation of a mixture is known as chromatography. The fluid in which the mixture is dissolved is called the mobile phase. It carries the fluid to another material named as the stationary phase. Various components of the mixture travel at different speeds due to which they separate. Chromatography can be either preparative or analytical. Preparative chromatography is concerned with the separation of a mixture's components for later use. Analytical chromatography deals with small amounts of material and is used to establish the presence and measurement of the relative proportions of analytes in a mixture. This book elucidates the concepts and innovative models around prospective developments with respect to chromatography. Some of the diverse topics covered herein address the varied techniques that fall under this category. This book will serve as a valuable source of reference for those interested in this area.
