cos Tof extraction de soufre

FPD : Flame Photometric Detector

Description. Limite de détection : < 100 ppb. Très sensible et sélectif: détecteur de choix pour les composés soufrés (Mercaptans, H 2 S, CS 2, COS, SO 2) ainsi que les pesticides stanneux.. Principe de fonctionnement: La combustion des composés dans une flamme Air/H 2 est très réductrice. De ce fait, la réduction du Phosphore en HPO et du soufre en S 2 provoque des ions excités qui ...
