Remove the collection system.
Rinse all components clean and allow them to dry.
Reinstall the rotor and the collection system.
The necessary cleaning method depends on the degree of the previously performed di-
gestion and its further use.
After a complete digestion it is sufficient to clean it several times with demineralized
water (e. g. 3x 20 ml).
If discoloration is noted or if carry-over is suspected, the vessels are cleaned by a
blank digestion using acid. In this case, the acid used for the particular application is
filled into the vessel, but no sample is added. After filling, the temperature program
for the application in question is started.
In the case of an incomplete digestion, mechanical removal of the undigested com-
pounds with cleansing wipes or a sponge can be recommended or a subsequent com-
plete digestion with a suitable acid mixture.
The glass rings installed in the cap for pressure control have to be cleaned from time to
time. This is necessary if the pressure signal of a pressure vessel varies significantly from
the signals of the other pressure vessels.
First remove glass prism from the lid.
Loosen the thumbscrew using a screwdriver.
Tilt carefully the coupling cap to one side in order to slide the glass prism slowly.
Where there are strong signs of wear (flaking, blistering, discoloration) on the pola-
rization foil at the side of the glass prism this is to be replaced (see below).
