Systems and method for minimizing the impact of water vapor or other interferent analyte on analyte concentration measurements in a gas exchange measurement system. A system is includes a gas source, first and second gas analyzers coupled to first and second gas flow lines and configured to measure first and second concentrations of a target analyte in the first and second gas flow lines, respectively, a sample chamber configured to hold a water saturable sample, and a water vapor selective element and having a first and second inputs fluidly coupling the gas source to first and second sides, respectively, of the water vapor selective element, and at least one output fluidly coupling the first side of the water vapor selective element to the first and second gas flow lines and a second output coupling the second side of the water vapor selective element to the second gas flow line.
