摘要
In the simultaneous recording of the voltage (U) between a working electrode and a reference electrode in a measuring instrument for potentiometric stripping analysis of a solution containing metal ions, and of the derivative of this voltage by means of a single-channel printer (8), the output signal of the measuring instrument, i.e. the voltage (U) between the electrodes, is supplied simultaneously to the printer (8) to be described in a diagram as a function of time, and to a deriving amplifier (9) to be derived. The output signal of the deriving amplifier (9), i.e. the derivative of the voltage (U), is used during the description of the voltage (U) as a function of time to mark in the diagram each point of time when the voltage (U) is changed.
