, Volume: 14( 1)Chromatography: Principles, Techniques, and Applications
Chromatography is a fundamental analytical technique used for the separation, identification, and quantification of components in complex mixtures. It plays a crucial role in pharmaceutical, chemical, environmental, and biological research. The technique is based on the differential distribution of compounds between a stationary phase and a mobile phase, leading to effective separation. Over the years, chromatography has evolved into multiple specialized forms, including paper chromatography, thin-layer chromatography (TLC), gas chromatography (GC), and high-performance liquid chromatography (HPLC), each offering unique advantages in terms of sensitivity, resolution, and speed. This article provides an overview of chromatography, its principles, types, and significant applications in various fields, emphasizing its importance in quality control, drug analysis, and research laboratories. The continued development of chromatographic techniques has greatly enhanced analytical accuracy and efficiency, establishing chromatography as an indispensable tool in modern science. Keywords: Chromatography, separation techniques, HPLC, gas chromatography, thin-layer chromatography, analytical chemistry Control
Chromatography is a versatile and widely used analytical technique that enables the separation, identification, and quantification of chemical substances in complex mixtures. The term “chromatography” originates from Greek, meaning “color writing,” because early techniques allowed the separation of colored compounds. The principle of chromatography relies on the distribution of analytes between a stationary phase and a mobile phase, resulting in differential migration and separation. Depending on the nature of the mobile and stationary phases, different chromatographic techniques have been developed to suit specific analytical needs. Paper chromatography and thin-layer chromatography (TLC) are simple, cost-effective methods widely used for qualitative analysis and preliminary investigations. Gas chromatography (GC) and high-performance liquid chromatography (HPLC), on the other hand, provide high resolution, sensitivity, and quantitative capabilities, making them essential in pharmaceutical analysis, environmental testing, and biochemical research. Chromatography is indispensable in drug development, as it allows precise identification and purity testing of active pharmaceutical ingredients, detection of impurities, and monitoring of degradation products. Beyond pharmaceuticals, chromatography finds applications in food analysis, forensic science, and clinical diagnostics, demonstrating its wide-ranging impact. The continuous evolution of chromatographic techniques, including the advent of ultra-performance liquid chromatography (UPLC) and Citation: Amir Khan.
