measurements. Their potentials can be verified by means of Metrohm’s ready-touse
redox standard solution. A second possibility is to perform the potential measurement
in a buffer solution saturated with quinhydrone and compare the measured
value with theoretical values given in literature.
It is advisable to check the redox electrode assemblies at regular intervals. For this
purpose, certified buffer solutions with specified redox potential or pH value should
be used.详细>
