Abstract

L'invention concerne des procédés et des systèmes mettant en oeuvre des volumes multiples de détection (50) destinés à la mesure électro-optique de la concentration de la masse et à la distribution commandée d'aérosols. Ces derniers sont transportés dans un courant gazeux (15). Un capteur réagissant à des particules comprises dans un volume d'échantillonnage relativement plus important (156) dans le courant gazeux est combiné avec un autre capteur réagissant à des particules comprises dans un volume d'échantillonnage relativement plus petit (162) dans le courant gazeux.
