Electrolytes are necessary liquid components for use with various electrodes or probe types. The solutions are designed to dissolve in a polar solvent and disperse uniformly through the solvent to produce an electrically conducting solution. Most soluble salts, acids, and bases are considered electrolytes. Background electrolytes are also essential for optimal capillary zone electrophoresis, while storage solutions guarantee equipment will work when needed. Premixed options are available to cut down on preparation time.
