Abstract

Un análisis electroquímico incluye un método para determinar con gran precision el tiempo en el que una muestra aplicada puentea una separacion entre loselectrodos de una celda electroquímica; el método incluye aplicar una pequena corrienteconstante a través de la separacion, al mismo tiempo que se vigila ladiferencia de potencial entre los electrodos; el tiempo en el que la muestra puentea la separacion se marca por una caída fuerte del potencial; se aplica unvoltaje constantedespués que se d etecta la muestra y se vigila la corriente y/o la carga a través de la muestra durante un periodo de tiempo; a partir de lacorriente o la carga medidas, se puede calcular la concentracion de analito que interesa.
