Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid (gas or solvent) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed. The different constituents of the mixture have different affinities for the stationary phase Adsorption Chromatography Experiment (TLC) Take a clean and dry chromatographic jar. To make sure that the environment in the jar is saturated with solvent vapours, a paper soaked in the mobile phase is applied to the walls. Add the mobile phase to the jar and close it. Maintain equilibrium. Mark the baseline on the adsorbent In this video I give a basic overview of GPC/SEC. In future videos I plan to go into more detail. Please comment or ask any questions.

Capillary electrophoresis (CE) is a family of electrokinetic separation methods performed in submillimeter diameter capillaries and in micro- and nanofluidic channels.Very often, CE refers to capillary zone electrophoresis (CZE), but other electrophoretic techniques including capillary gel electrophoresis (CGE), capillary isoelectric focusing (CIEF), capillary isotachophoresis and micellar. Ion chromatography (or ion-exchange chromatography) separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids.However, ion chromatography must be done in conditions that are one unit away from the isoelectric point of a protein Electrophoresis: Overview, Principles and Types. Electrophoresis involves the migration of charged particle or molecules under the influence of an applied electric field.; Various important biomolecules such as peptides, amino acids, proteins, nucleic acid and nucleotides has ionizable groups and they exist in solution as electrically charged particles either as cations or as anions at any.

Analytical Technologies in Biotechnology Prof. Dr. Ashwani K. Sharma Department of Biotechnology Indian Institute of Technology Roorkee Module - 3 Chromatographic Methods Lecture - 5 Gel Filtration Chromatography Previous lecture, we have discussed about ion exchange chromatography. In ion exchange chromatography, the properties of charge which a particular analyte carries on itself are. interaction chromatography (HIC) is an ideal separation method. In my experience, HIC is finding dramatically increased use both in laboratory and production processes. Since the molecular mechanism of HIC relies on unique structural features, it serves as an orthogonal method to ion exchange, gel filtration and affinity chromatography Column chromatography is used by an organic chemist to separate liquids and solids from a solution. In a column of absorbents which is silica gel or it may be alumina gets loaded in a column filled with impurities when conducting an experiment. This mixture flows down the column, and the component of the sample receives separated by splitting. gel. For easier separations, ratios closer to 30 : 1 are effective, for difficult separations, more silica gel is often required. However, by using more silica gel, the length of time required for the chromatography is extended. The density of powdered silica gel is about 0.75 g per mL.

Pulsed Field Gel Electrophoresis (PFGE) is a technique used for the separation of large deoxyribonucleic acid (DNA) molecules by applying to a gel matrix an electric field that periodically changes direction.; As DNA larger than 15-20kb migrating through a gel essentially moves together in a size-independent manner, the standard gel electrophoresis technique was unable to separate very large. Thin Layer Chromatography is a technique used to isolate non-volatile mixtures. The experiment is conducted on a sheet of aluminium foil, plastic, or glass which is coated with a thin layer of adsorbent material. The material usually used is aluminium oxide, cellulose, or silica gel. On completion of the separation, each component appears as. Adsorption chromatography has been reported for a variety of small molecular weight compounds on Sephadex (Gorbach and Henke, 1968; Sweetman and Nyhan, 1968) and on Bio-gel (John et al., 1969). Although many of these molecules have a high affinity for these gels, none are irreversibly bound and all elute with little or no smearing
For a stronger layer, polyvinyl alcohol or polyvinyl pyrollidone can be added to a TLC grade silica gel (without G or H binders) in a level of 1-2% by weight as a polymeric binder Sephacryl High Resolution chromatography resins is a highly versatile gel filtration resins that offers a wide range of fractionation capabilities. The matrix of Sephacryl High Resolution resins is a cross-linked copolymer of allyl dextran and N,N'-methylene bisacrylamide. This crosslinking gives good rigidity and chemical stability
But interestingly this method of chromatography finds less use in research and industry. Instead the reverse phase chromatography is widely used. This is because of the wide advantages that method offers. Normal Phase Chromatography principle. In routine chromatography, sand or silica gel which is polar in nature is used as stationary phase Introduction. Endeavors in capillary electrophoresis (CE) began as early as the late 1800's. Experiments began with the use of glass U tubes and trials of both gel and free solutions. 1 In 1930, Arnes Tiselius first showed the capability of electrophoresis in an experiment that showed the separation of proteins in free solutions. 2 His work had gone unnoticed until Hjerten introduced the use. Size exclusion chromatography is based on a relatively simple principle, but can involve complicated considerations when actually performing analyses or analyzing results.
