Title (EN) POTENTIOSTAT/GALVANOSTAT WITH DIGITAL INTERFACE
(FR) POTENTIOSTAT/GALVANOSTAT À INTERFACE NUMÉRIQUE
Abstract:
(EN) A potentiostat/galvanostat employs a controller for providing digital control signals to a digital-to-analog converter (DAC) that generates an analog output signal in response to digital control signals. A high current driver produces a high current output in response to the analog output signal from the DAC. A high current monitor monitors the output from the high current driver to produce a feedback signal for the high current driver to control the current produced by the high current driver and to produce an output dependent on the current supplied from the high current driver for monitoring by the controller. A counter electrode contact for a counter electrode is connected with the output of the high current monitor. A working electrode contact for a working electrode is electrically connected with a fixed stable voltage potential to enable electrochemical analysis of material between the counter electrode and the working electrode.
(FR) L'invention concerne un potentiostat/galvanostat qui utilise un contrôleur pour fournir des signaux de commande numériques à un convertisseur numérique-analogique (CNA) qui génère un signal de sortie analogique en réponse à des signaux de commande numériques. Un circuit d'attaque à courant élevé produit une sortie à courant élevé en réponse au signal de sortie analogique du CNA. Un dispositif de surveillance de courant élevé surveille la sortie du circuit d'attaque à courant élevé pour produire un signal de rétroaction pour le circuit d'attaque à courant élevé pour commander le courant électrique produit par le circuit d'attaque à courant élevé et pour produire une sortie dépendant du courant fourni par le circuit d'attaque à courant élevé pour une surveillance par le contrôleur. Un contact de contre-électrode pour une contre-électrode est relié à la sortie du dispositif de surveillance de courant élevé. Un contact d'électrode de travail pour une électrode de travail est connecté électriquement à un potentiel à tension stable fixe pour permettre l'analyse électrochimique de la matière entre la contre-électrode et l'électrode de travail.
