Abstract
(EN)
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.

Dans un enregistrement simultane de la tension (U) entre une electrode de travail et une electrode de reference dans un instrument de mesure d"analyse par extraction potentiometrique d"une solution contenant des ions metalliques, et de la derivee de cette tension au moyen d"une imprimante a un seul canal (8), le signal de sortie de l"instrument de mesure, c"est-a-dire la tension (U) entre les electrodes, est envoye simultanement a l"imprimante (8) sous forme d"une fonction du temps dans un diagramme, et a un amplificateur de derivation (9). Le signal de sortie de l"amplificateur de derivation (9), c"est-a-dire la derivee de la tension (U), est utilise pour la description de la tension (U) comme une fonction du temps pour marquer dans le diagramme chaque point de temps lorsqu"il y a un changement de la tension (U).
