Abstract

Hot and humid gases are sampled for analysis. The temp. of the gas is maintained above its dew point and diluted in a regulation chamber. Dilution is performed with a ballast inert gas and the mixt. fed to an analysing appts. The gas e.g. Hydrogen-sulphide enters the device at input (4) and has its temp. regulated in a compressed path (5) through an auto clave (1). The closing inert gas is applied at point (7) to the upstream side of a jet (2') for mixing and output (13). Monometers (6) and (12) monitor gas flow in auto clave.
