Amperometric oxygen sensors

L. C. Clark first suggested in 1956 that the test solution be separated from an amperometric oxygen sensor by a hydrophobic porous membrane, permeable only for gases (for a review of the Clark electrode see [88]). The first potentiometric sensor of this type was the Severinghaus CO2 electrode [150], with a glass electrode placed in a dilute solution of sodium hydrogenocarbonate as the internal sensor (see fig. 4.10). As an equilibrium pressure of CO2, corresponding to the CO2 concentration in the test solution, is established in the... [Pg.77]

A major advance in the performance of amperometric oxygen sensors has been achieved by placing both the cathode and the anode behind the oxygen-permeable membrane (Fig. 7.4). This sensor is known as the Clark oxygen electrode. [Pg.210]

Amperometric oxygen sensors show a large dependence on temperature, an increase of current of 2% °C is observed. This is caused by the temperature dependence of the diffusion coefficient for oxygen in the membrane. A temperature sensitive element such as a thermistor is therefore often incorporated in the cell to allow electronic compensation for this source of error. It is obvious that... [Pg.4365]
