2.4 Generator electrode without diaphragm
The 6.0345.100 generator electrode without diaphragm poses no
handling problems and is easy to clean. It only requires one reagent
and is quickly ready for use (no moisture depots in the diaphragm!).
The generator electrode without diaphragm is the best choice for
most applications. It is particularly suitable for use with very polluting
samples.
2.4.1 Reagents
Only use those reagents which are specially intended for use with
generator electrodes without diaphragm; see the reagent manufac-
turer's documentation.
2.4.2 Cleaning
The electrolyte solution can normally be exchanged without any spe-
cial cleaning of the parts being necessary. If cleaning is necessary
then care should be taken that the Pt grid of the generator electrode
is not damaged.
Pollutants containing oil:
Clean with a solvent (e.g. hexane) and then rinse with ethanol.
Salt-like deposits:
Clean with water and then rinse with ethanol.
Dry all parts thoroughly after cleaning. A hot-air blower can be used
for this. If the parts are dried in a drying oven take care that the tem-
perature does not exceed 70°C (plastic components!).
