In chromatography, there are two major techniques used. The first is capillary electrophoresis, in which the sample is passed through an electrically conductive gel where it is detected by the electric charge produced by the sample tip. This gel is known as the stationary phase. The second technique used in chromatography is infrared or chemilusmiecular separation. This separation technique uses the mutual coupling of internal and external electromagnetic light to mobility and adsorption properties of the sample in a stationary phase.
Both of these chromatography techniques produce separation results by separating the analytes from the molecules that they are in contact with. In chromatography, there is a third technique called Ion chromatography, which separates analytes from other substances in a stationary phase by the effect of their presence on electrically charged surfaces such as the carbon dioxide molecule. All the different chromatography techniques are based on the same concepts of separation of analytes from a stationary phase, which can either be water, serum-based buffer, or some other media. Separation of different analytes and probes is accomplished using different methods, but all chromatography relies on one or more steps that set up the conditions for the separation of the analytes from the other substances.
