Developing or optimizing a separation using buffers that contain detergents. Select detergents that are compatible with the sample. A detergent must be neutral, zwitterionic or have the same charge as the IEX medium. A sample is introduced, either manually or with an autosampler, into a sample loop of known volume. A buffered aqueous solution known as the mobile phase carries the sample from the loop onto a column that contains some form of stationary phase material. This is typically a resin or gel matrix consisting of agarose or cellulose beads with covalently bonded charged functional groups. Equilibration of the stationary phase is needed in order to obtain the desired charge of the colu… in your shining eyes tab
