1. A system, comprising:
an analyzer configured to detect moisture, or interferent(s), or both, in a process gas, wherein the analyzer comprises:
an absorption cell enclosing and conducting the process gas;a pressure control device configured to reduce a pressure of the process gas inside the absorption cell to provide de-pressurized process gas sample at a pressure lower than an ambient pressure of the process gas;a light emitting device configured to transmit light through the de-pressurized process gas inside the absorption cell;a photodetector configured to detect an intensity of the light transmitted through the de-pressurized process gas and exiting the absorption cell; andelectronic circuitry configured to detect moisture, or one or more interferents, or both, in the process gas, using variable gas compensation logic, wherein the variable gas compensation logic is configured to compensate moisture detection for the interferents utilizing one or more X values associated with certain absorption features of the interferents and one or more ratio functions of the interferents. |
