Cleaning the cells
Clean cells thoroughly between measurements, especially between different types
of sample. Cross-contamination between samples can seriously affect the results.
Cleaning the universal ‘Dip’ cell
Caution!
Do
not
immerse the complete cell. Only the sample electrodes must dip in
to the dispersant, as shown below.
Clean the dip cell electrodes regularly. They are made of solid palladium and can be
cleaned physically and chemically.
To clean the cell:
1.
Immerse the electrodes in a gentle ultrasound bath (30 Watts) for five to 15
minutes before use. Use the dispersant used for the previous sample as the
cleaning fluid. If this dispersant contains additives such as surfactants, follow
this by ultrasonicating for two minutes in the pure solvent.

Warning!
Take care: ultrasonication can produce a fine aerosol of the bath liquid.
2.
Remove the electrodes from the bath and rinse them with pure solvent. A pipe
cleaner can be used for
gentle
cleaning of electrodes.
3.
To protect the dip cell after cleaning, we recommend placing it in an empty
cuvette for storage.
Before making a measurement, rinse the electrodes and cuvette with the sample to
be measured.
When changing the sample, thoroughly rinse the electrodes with pure dispersant.
