Abstract: A method is provided for measuring an electrolytically-active species concentration in an aqueous or non-aqueous solution for use in providing control of the concentration of the species in a source solution thereof based on the measurements. In the method, a sample containing an electrolytically-active species is added into a measurement cell that has a working electrode and an auxiliary electrode, and a constant current is applied to the measurement cell while the working and auxiliary electrodes are in contact with the sample with monitoring of voltage difference across the electrodes until a change in the voltage difference is detected. A feedback signal is generated based on a parameter of the change in the voltage difference that is directly proportional to the amount of the electrolytically-active species in the sample, which can be used for process control. An apparatus is also described.

Abstract: Se proporciona un método para medir una concentración de especies electrolíticamente activas en una solución acuosa o no acuosa para el uso en la provisión de control de la concentración de la especie en una solución de origen de la misma basada en las mediciones. En el método, una muestra que contiene una especie electrolíticamente activa se adiciona en una celda de medición que tiene un electrodo de trabajo y un electrodo auxiliar, y una corriente constante se aplica a la celda de medición mientras que los electrodos de trabajo y auxiliares están en contacto con la muestra con el monitoreo de la diferencia de voltaje a través de los electrodos hasta que se detecta un cambio en la diferencia de voltaje. Una señal de retroalimentación se genera en base a un parámetro del cambio en la diferencia de voltaje que es directamente proporcional a la cantidad de la especie electrolíticamente activa en la muestra, que se puede utilizar para el control del proceso. También se describe un aparato.
