Abstract

Moniteur de gaz à capture électronique. Pour analyser un gaz contenant un gaz traceur à capture électronique, on le fait passer dans une colonne de criblage moléculaire, puis entre deux électrodes, où le gaz traceur réduit le flux d'électrons, ce qui permet d'en déterminer la concentration dans l'échantillon à analyser, par référence à une courbe d'étalonnage. Applicable notamment à l'analyse des fumées présentes dans l'air, relâchées dans l'atmosphère par les installations industrielles et les centrales génératrices d'énergie à combustible fossible.
