Abstract

Analyse de composés organiques volatils en faibles concentrations (p.p.b. ou p.p.t.), effectuée par passage d'un échantillon en écoulement dans un piège à condensation renfermant quelques milligrammes de matières de remplissage, selon une vitesse comprise entre 50 et 1000 cm/sec. Ensuite, on chauffe le piège afin de provoquer la désorption de l'échantillon ainsi concentré, puis on évacue ce dernier en vue d'effectuer une analyse.
