Abstract

A simple sulphur-dioxide meter is described which has been used in a study of experimental respiratory pathology. The method is based on the changes in electrical conductivity produced by the reaction of sulphur dioxide with a solution of hydrogen peroxide.

Sommaire

On décrit un simple appareil de mesure à l'anhydride sulfureux qui a été utilisé pour une étude de la pathologie respiratoire expérimentale. Cette méthode est basée sur les modifications de la conductivité électrique provoquées par la réaction de l'anhydride sulfureux avec une solution d'eau oxygénée.

Zusammenfassung

Es wird ein einfaches Gerät zum Messen von Schwefeldioxid beschrieben, das zu einer Untersuchung der experimentellen Atmungspathologie eingesetzt wurde. Das Verfahren fu\t auf Änderungen in der elektrischen Leitfähigkeit, die durch die Reaktion des Schwefeldioxids min einer Lösung des Wasserstoffsuperoxids entsteht.
