On the one hand, CE has been the subject of much basic research devoted to instrumentation and other aspects of this technique. On the other hand, CE has become an interesting alternative in routine analysis, being recognised and established as an acceptable and reliable alternative to traditional analytical methods by many industries, law courts and government regulatory agencies . In the case of small ions, the separation and determination of metal ions and inorganic anions by CE have received considerable attention.
In conclusion, there appears to be a very promising and brilliant future for CE techniques as the number of studies, developments, and applications continue to multiply. L. Marina, A. Rı´os and M. Valca (in seconds, not minutes) using microchip technology, and narrower and shorter capillaries will be employed in array format in order to achieve highly efficient and high-throughput analysis. Multiplexing systems will be used not only to sequence DNA but for simultaneous multisample analysis. In addition to its use as an analytical tool, a continued and expanded role of CE in the determination of physicochemical parameters is foreseen.
Sample ions are mixed with the carrier ampholytes that span the desired pH range, and the mixture is loaded onto the capillary. If an electric field is applied, the ampholytes build up a pH gradient and the sample analytes migrate until they reach a region of pH where they become electrically neutral and therefore stop migrating. Then, zones are focused until a steady-state condition is reached. EOF should be eliminated in CIEF and an additional step is necessary to force the zones pass the detector [1,8].
