METHOD FOR DETERMINING THE CONCENTRATION OF ONE OR MORE POLLUTANTS IN A CERTAIN ATMOSPHER.

摘要

Apparatus for measuring one or more polluting components in a certain atmosphere, consisting of a carrier gas supply system (1, 2, 3, 4, 5, 6, 7), a sample cock (8) for the supply of a certain amount of gas to be examined together with a carrier gas, an oven (11) containing a separating means for the components of the gas to be examined, a detector (12), an eliminator (13) for eliminating components which are not to be determined, and an integrator or peak height measuring system (14) for indicating the concentration of the component(s) which have been determined.
