PCT No. PCT/DE92/00157 Sec. 371 Date Mar. 14, 1994 Sec. 102(e) Date Mar. 14, 1994 PCT Filed Feb. 27, 1992 PCT Pub. No. WO93/17304 PCT Pub. Date Sep. 2, 1993.In the method, the totality of the gases is conducted through an absorption cell. A reference cell contains a reference gas. The cells are optically transirradiated and a signal representing a quantity for the mass flow to be identified is generated in a detector which picks up the optical radiation emerging from the cells.
