Capillary electrophoresis i.k.
Before each analysis are performed only the last two steps.
Another method consists in washing with a strong acid or with organic solvents such as
methanol, dimethylsulfoxide or detergents.
Thermal regulation
A strong dependence of the input volume and the migration time of the viscosity necessitates
thermostation with accuracy ± 0.1 °C using a water or air bath. Although thermostating in
liquid is more efficient, air flow of about 10 m / s are suitable for heat dissipation in HECE to
5 W / m. Air temperature control is technically feasible easier, so almost everywhere this
method is used.
High voltage power source
HECE requires a source of direct current with voltageabout 30 kV and a current
strength about 200 to 300 uA
