Title: Installation for analyzing an atmosphere

Abstract: Installation for analyzing the level of at least one element, from at least two initial gas sources (S.sub.1, S.sub.2, . . . ) in a sampling procedure, using at least one analyzer (A.sub.1, A.sub.2, . . . ) capable of analyzing the element, including: at least two sources (S.sub.1, S.sub.2, . . . ) of initial gases to be analyzed; at least two tapping lines (L.sub.p1, L.sub.p2, . . . ), each line being connected in its upstream part to one of the initial gas sources, and in its downstream part to a respective flow-directing component (V.sub.1, V.sub.2. . . ); at least two discharge lines (L.sub.E1, L.sub.E2, . . . ), each discharge line being connected in its upstream part to one of the directing components and in its downstream part to a discharge or to a storage point (E.sub.1, E.sub.2, . . . ); at least two secondary lines (L.sub.s1, L.sub.s2, . . . ), each secondary line being connected in its upstream part to one of the directing components and, in its downstream part, to a collection point (R), each directing component being capable of directing a sample from the initial gas source which is associated with it to its respective discharge line or to the collection point via its respective secondary line; a tertiary line (L.sub.T), connected in its upstream part to the collection point and in its downstream part to a discharge or to a storage point (E); at least one analysis line (L.sub.Ai), connected in its upstream part to the tertiary line and in its downstream part to at least one of the at least one analyzers.
