1. A method for equilibrating a dissolved calibrant gas in an aqueous calibrant fluid, which is adapted to be used to calibrate a gas sensor within a housing, comprising:

  • providing a housing containing an aqueous calibrant fluid adapted to contain at least one calibrant gas dissolved therein,providing a gas sensor within said housing, which is adapted to measure a concentration of dissolved gas in said aqueous calibrant fluid when said sensor is in direct contact with said aqueous calibrant fluid;

    providing a gas phase, comprising at least one calibrant gas, in said housing and out of direct contact with said gas sensor;

    forming an interface between said aqueous calibrant fluid and said gas phase positioned out of direct contact with said gas sensor, wherein said interface is substantially proximate to said gas sensor; and

    equilibrating said aqueous calibrant fluid with said gas phase comprising said at least one calibrant gas;

    whereby forming an equilibrated calibrant fluid containing said at least one calibrant gas dissolved therein.
