Abstract
A voltage control circuitry for a detection cell is described, where the detection cell is adapted for determining an electrical property of a sample in a detection cell volume of the detection cell. The voltage control circuitry comprises a power supply adapted for providing a voltage to the detection cell, and a power evaluation unit adapted for determining an actual power dissipation in the detection cell volume. The voltage control circuitry further comprises a control unit adapted for comparing the actual power dissipation with a desired power dissipation, and for regulating the power supply's voltage in a way that the actual power dissipation is driven towards the desired power dissipation.
