This report provides a state of the art summary and evaluation of the methods for the determination of total gas in water samples. The hollow fiber, the hollow tube, and the flat membrane probes were evaluated. A flat surface probe was developed that has a low dead space, high permeability and a low tendency to form bubbles under supersaturated conditions. Methods for sampling and storage of supersaturated water samples were also evaluated. A comparison of field and laboratory methods is presented.
