METHOD AND APPRATUS FOR MEASURING CHEMICAL ION CONCENTRATION USING A FEEDBACK-CONTROLLED TITRATOR |
摘要 |
There is provided a method and device for measuring an ion concentration of a sample. The method comprises exposing a chemical sensor to the sample to provide an electrical output signal 5 representing said ion concentration and controlling a titrator exposed to the sample to release or absorb a quantity of ions to the sample. The method may use feedback means comprising Pulse Width Modulation control to drive the titrator such that the sample maintains a stable ion concentration. |
