Abstract
An improved method for the separation of anions using capillary electrophoresis techniques. Both organic and inorganic anions may be separated. Using precise control of the temperature of the fluid in the capillary column; the migration speed and order of migration of the anions may be controlled to improve the selectivity of the process. Further, close temperature control provides a high degree of repeatability for samples and enables one to track and identify specific anions.
