This can be useful in forensic investigations for DNA finger-printing or in drug test to see the components in a person’s blood plasma. Webchromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid. WebIon-exchange chromatography (IEC) is one of the most frequently used techniques for the purification of proteins and other biomolecules. It is based on the different degrees of electrostatic interactions between the stationary phase and solutes. Various cation- and anion-exchange chromatography media have been developed for protein purifications. northern lights 12kw generator
