ABSTRACT:
A biochemical device and method for the determination of dissolved gases in solution is provided which employs a dry electrode/sample interface. Dissolved oxygen or other gas concentration in a liquid sample is measured by its diffusion through a selectively permeable membrane which is an integral part of a disposable receptacle. The receptacle makes contact with a gas-sensing electrode at the locus of the selectively permeable membrane whereby the determination of the concentration of said gas is made by the electrode without ever touching the liquid sample.
