Multidimensional Electrodriven Separations 213

9.15 CONCLUSIONS

Electrodriven techniques are useful as components in multidimensional separation
systems due to their unique mechanisms of separation, high efficiency and speed.
The work carried out by Jorgenson and co-workers has demonstrated the high effi-
ciencies and peak capacities that are possible with comprehensive multidimensional
electrodriven separations. The speed and efficiency of CZE makes it possibly the
best technique to use for the final dimension in a liquid phase multidimensional sep-
aration. It can be envisaged that multidimensional electrodriven techniques will
eventually be applied to the analysis of complex mixtures of all types. The peak
capacities that can result from these techniques make them extraordinarily powerful
tools. When the limitations of one-dimensional separations are finally realized, and
the simplicity of multidimensional methods is enhanced, the use of multidimen-
sional electrodriven separations may become more widespread.
