Abstract

La présente invention touche à la médecine et à la technique médicale et peut servir à mettre en évidence de la propanone-2 dans l'air de respiration, ainsi qu'à dépister et diagnostiquer l'hyperkétonémie. Elle présente l'avantage technique de permettre une mise en évidence précise de la propanone-2, dont la présence est détectée à l'aide d'un capteur chimique pour lequel on utilise comme surface sensible un copolymère polyvinylidène-fluorhydrexa-fluopropylène, l'agent physico-chimique associé à ladite surface sensible étant un résonateur piézo-électrique de classe AT à fréquence d'oscillation de 20 MHz, tandis que la masse de la surface sensible des électrodes de ce dernier représente 50-100 microgrammes, et le volume de la cellule réactive 0,4 cm3.
