Abstract
As has been shown in Chapter 3, the separation efficiency that can be obtained in CE is proportional to the voltage that is applied. A high-voltage source is therefore a prerequisite for CE. Commercial instruments have sources with an upper limit of usually 30 or 35 kV With higher voltages the electrical insulation of the various parts of the CE set-up becomes problematic, with spontaneous sparking and a risk of serious damage of sensitive electronic components as a result. A high precision and low drift of the applied voltage is of course important for the reproducibility of the migration times of analytes.
