Abstract:
1. A gas-solution equilibrium device for use in a liquid sample gas analyzer comprising: a temperature-controlled, thermally-conductive mandrel; a coil of gas-permeable tubing wrapped around the mandrel, the gas-permeable tubing having an inlet and an outlet; and a housing having an internal space containing the temperature-controlled, thermally-conductive mandrel, the coil of gas-permeable tubing and a volume of gas wherein the coil of gas-permeable tubing has a predefined linear length and the gas-permeable tubing has a predefined wall thickness, the combination of which together is capable of equilibrating a liquid passing through the coil at a predefined flow rate with the gas within the internal space to provide a gas calibration solution in real time at the outlet of the tubing for the liquid gas analyzer.
