Chromatography: An Invaluable Tool in Research and the Industry deals with the technique of chromatography and its major applications in the field of research. It consists of recycle HPLC technique used for the purification of natural products and basic principles involved in MLC. It provides the reader with the fundamental concept of chromatography so as to understand its application in the extraction of natural products, analyze posttranslational modifications and compare an electronic nose based on ultrafast gas chromatography. This book also discusses about reminder of systems of production and chromatography-based recovery of recombinant protein biopharmaceuticals, strong cation exchange chromatography in analysis of posttranslational modifications, chromatographic removal of endotoxins, dissolution testing of single- and dual-component thyroid hormone supplements, recombinant passenger proteins can be conveniently purified by one-step affinity chromatography and surfactant modified/mediated thin-layer chromatographic systems for the analysis of amino acids.
