Abstract
Systems and methods of compensating analyzer offsets in a dual analyzer gas analysis systems. A flow swapping device when in a first configuration delivers the chamber influent to a first gas analyzer, and the chamber effluent delivered to a second gas analyzer. At any arbitrary time, the configuration of the flow swapping device can be switched wherein chamber influent is delivered to the second gas analyzer, and chamber effluent is delivered to the first gas analyzer. By changing the configuration of the match valve, the gas analyzer initially connected to the chamber effluent is connected to the chamber influent. Conversely, the gas analyzer initially connected to the chamber influent is connected to the chamber effluent enabling a determination of offset error between the analyzers. The various embodiments are approximately two-times faster than known methods for dual analyzer systems; the reduced time translates to an overall faster gas exchange measurement.
