Abstract
L'INVENTION CONCERNE UNE METHODE VOLTAMETRIQUE POUR DETERMINER AUTOMATIQUEMENT ET DE FACON REPETITIVE LES QUANTITES D'UNE OU DE PLUSIEURS SUBSTANCES, CES QUANTITES ETANT COMPRISES ENTRE 10 ET 10MOLEL (0,1-1000MICROGRAMMES PAR LITRE) SELON UN PROGRAMME SE REPETANT SANS INTERRUPTION ET REGULIEREMENT SUR DE LONGUES PERIODES. L'INVENTION CONCERNE EGALEMENT UN APPAREIL POUR LA MISE EN OEUVRE DE LA DITE METHODE, COMPRENANT UNE CELLULE DE MESURE 1 EQUIPEE D'UNE ELECTRODE A GOUTTE PENDANTE LOCALISEE EN12 ET DE MOYENS 8 POUR RENOUVELER CETTE GOUTTE PREALABLEMENT A CHAQUE DETERMINATION. LE PRETRAITEMENT D'UNE NATURE PHYSIQUE ETOU CHIMIQUE EST EFFECTUE SANS INTERRUPTION EN DEHORS DE LA CELLULE DE MESURE.
