MULTI-COMPONENT GAS ANALYSIS APPARATUS

摘要

The apparatus which measures the concentration of two or more gases such as oxygen and nitric oxide in a gas mixture has at least two compartments (7 and 22) in which the most easily reduced gas is reduced in the first compartment (7) and the next easily reduced gas is reduced in the second compartment (22) and so on until all the gases of interest have been reduced. The current, as measured by ammeters (8 and 24), required to electrochemically reduce each gaseous component being measured in the gas mixture is directly proportional to the concentration of that gas in the mixture.
