Chromatography is a set of techniques used to separate mixtures in a chemistry lab setting. The word chromatography means "color writing" and some of the first experiments in chromatography. Next, remember that you are not alone. While every problem is unique, many people will have experienced similar problems and will have found solutions. Here we present some of the most common problems and their most likely solutions (Tab. 2). Table 2. Common problems encountered during column chromatography and their solutions. 2D TLC.

Chromatographic Systems: Maintenance and Troubleshooting, Second Edition provides a clear and concise guide for chromatographic maintenance. This book covers troubleshooting and repair procedures that can be utilized by both experienced and inexperienced chemists and technicians to reduce instrument down-time.
This edition is divided into two parts. Chromatography Today provides a comprehensive coverage of various separation methods: gas, liquid, thin-layer, and supercritical fluid-chromatography, and capillary electrophoresis.
Particular attention is paid to the optimization of these techniques in terms of kinetic parameters and retention Edition: 5. In Part A the theoretical basis of individual separation methods is explained and the technical aspects are illustrated. It includes the theory of gas and liquid chromatography as well as specific chromatographic techniques, such as size-exclusion, planar, ion, and affinity chromatography as well as various electrokinetic separation techniques.2/5(3).
Fundamentals of Preparative and Nonlinear Chromatography, Second Edition is devoted to the fundamentals of a new process of purification or extraction of chemicals or proteins widely used in the pharmaceutical industry and in preparative process permits the preparation of extremely pure compounds satisfying the requests of the US Food and Drug Administration.

Introduction Chromatography is a physical method of separation in which the components to be separated are distributed between two phases one of which is stationary (stationary phase) while the other (the mobile phase) moves through it in a definite direction.
