|Abstract: ||An improved method based on equilibrium partitioning between water samples and an inert host gas, introduced
after sampling, is proposed for determining multiple species of dissolved gases in brackish water. The method
itself, and the most convenient equations for describing gas solubilities in brackish waters, is described in detail.
The method allows the rapid characterization of several sites and represents a useful tool for geochemical surveys.
A comparison between replicate samples analyzed using different procedures demonstrates the efficiency of the
method and indicates that the abundances of the main dissolved gases can be obtained, which can then be used
to determine underlying geochemical processes. A Microsoft Excel worksheet is provided to easily calculate the
concentration of dissolved gas species.|
