This can also be used in secondary or primary colors in ink experiments. This method has been largely replaced by thin layer chromatography , however it is still a powerful teaching tool. Two way paper chromatography , also called two dimensional chromatography , involves using two solvents and rotating the paper 90 in between. This is useful for separating complex mixtures of similar compounds, for example, amino acids . R sub sub value The retention factor R sub sub may be defined as the ratio of the distance traveled by the substance to the distance traveled by the solvent. R sub sub values are usually expressed as a fraction of two decimal places but it was suggested by Smith that a percentage figure should be used instead.

unreferenced date September 2011 Affinity electrophoresis is a general name for many analytical methods used in biochemistry and biotechnology . Both qualitative and quantitative information may be obtained through affinity electrophoresis. The methods include the so called mobility shift electrophoresis, charge shift electrophoresis and affinity capillary electrophoresis . The methods are based on changes in the electrophoresis electrophoretic pattern of molecules mainly macromolecules through biospecific interaction or complex formation . The interaction or binding of a molecule, charged or uncharged, will normally change the electrophoretic properties of a molecule. Membrane proteins may be identified by a shift in mobility induced by a charged detergent . Nucleic acid s or nucleic acid fragments may be characterized by their affinity to other molecules. The methods has been used for estimation of binding constant s, as for instance in lectin affinity electrophoresis or characterization of molecules with specific features like glycan content or ligand binding. For enzymes and other ligand binding proteins, onedimensional electrophoresis similar to counter electrophoresis or to immunoelectrophoresis rocket immunoelectrophoresis , affinity electrophoresis may be used as an alternative quantification of the protein. Some of the methods are similar to affinitychromatography by use of immobilized ligands .

A chromatography detector is a device used in gas chromatography GC or liquid chromatography LC to visualize components of the mixture being eluted off the chromatography column. There are two general types of detectors destructive and non destructive. The destructive detectors perform continuous transformation of the column effluent burning, evaporation or mixing with reagents with subsequent measurement of some physical property of the resulting material plasma, aerosol or reaction mixture . The non destructive detectors are directly measuring some property of the column effluent for example UV absorption and thus affords for the further analyte recovery. Destructive detectors Flame ionization detector . The column effluent is injected into hydrogen flame and the flame conductivity is measured. Only used in GC. Aerosol based detector NQAD . The column effluent is nebulized, the mobile phase evaporated, a water shell condensed on it and then it is detected. Very sensitive detection for reverse phase applications. Flame photometric detector , FPD . Column eluate is burned in hydrogen flame. The light of the flame is filtered through an optical filter. Allows the detection of sulfur and phosphorus.
