Chromatography is a laboratory method employed for separating mixtures. It involves a fluid, known as the mobile phase, in which the mixture dissolves. This mobile phase moves the fluid to another substance termed the stationary phase. Differential speeds of various mixture components facilitate their separation. Chromatography can assume either a preparative or analytical role. Preparative chromatography focuses on segregating mixture components for subsequent utilization. In contrast, analytical chromatography is geared towards minute material quantities and serves to ascertain the presence and quantify the relative proportions of analytes within a mixture. Chromatography is a technique that has undergone rapid development over the past few decades. Most of the topics introduced in this book cover new techniques and the applications of chromatography. Those with an interest in this field would find this book helpful.
