ABSTRACT:
To provide a highly reliable apparatus for measuring mercury contained in the gaseous medium, in which the outlet port3bof the reducing tube and the gas-liquid separator, both susceptible to deposition of stain, can be automatically cleaned to avoid reduction of the sensitivity of the measuring instrument, the apparatus for measuring mercury contained in the gaseous medium includes a reducing tube3for reducing divalent mercury contained in a gaseous medium to zerovalent mercury, a gas-liquid separator4for removing a liquid component (drain) from the gaseous medium that has passed through the reducing tube3, a measuring instrument6for measuring the quantity of the mercury contained in the gaseous medium delivered from the gas-liquid separator4, and a cleaning system10for running a cleaning liquid from an outlet port of the reducing tube3past the gas-liquid separator4to emerge outwardly of the gas-liquid separator4.
