Abstract
Dispositif pour déterminer les concentrations de substances, comprenant un carter contenant un monochromateur et un appareil photométrique, ainsi qu'un indicateur traversé par la lumière du monochromateur (optode). L'indicateur 12 est déplaçable à l'intérieur de l'optode 1 par voie mécanique ou sous l'action de champs magnétiques ou électriques. Applications: mesure de la concentration de gaz du sang au niveau de la peau ou d'un tissu.
