Title
(EN) ANALYZER CIRCUITRY FOR ANALYZING SAMPLES ON ION SENSITIVE ELECTRODES
(FR) CIRCUITS ANALYSEURS SERVANT A ANALYSER DES ECHANTILLONS SUR DES ELECTRODES SENSIBLES AUX IONS
Abstract
(EN)
An analyzer is adapted to receive disposable ion selective electrode sensors. The sensors are used to measure ion concentrations in fluid samples. The analyzer has amplifier circuitry which is protected by relays to prevent the negative effects of static discharge which may arise from the repeated insertion and removal of the disposable sensors. A microcontroller under the control of software controls algorithms for detecting removal of the calibration gel, the application of a sample to the analyzing system and the analysis of that sample.
(FR)
Un analyseur est conçu pour recevoir des capteurs à électrode sensible aux ions et à usage unique. Les capteurs sont utilisés pour mesurer des concentrations ioniques dans des échantillons de fluide. L'analyseur comprend des circuits amplificateurs qui sont protégés par des relais afin de prévenir les effets négatifs de décharges statiques qui peuvent résulter de l'introduction et de l'enlèvement répétés des capteurs à usage unique. Un microprocesseur commandé par logiciel commande des algorithmes permettant de détecter l'enlèvement du gel d'étalonnage, l'application d'un échantillon sur le système d'analyse et l'analyse de cet échanitllon.
