7 Operation and maintenance
Warning
Never open the housing of the instrument. The instrument could be
damaged by this. There is also a risk of serious injury if live components
are touched.
There are no parts inside the housing which can be serviced or replaced
by the user.
7.1 General
The 909 UV Digester requires appropriate care. Excess contamination of
the instrument may result in functional disruptions and a reduction in the
lifetime of the sturdy mechanics and electronics of the instrument.
Severe contamination can also have an influence on sample digestion.
Regular cleaning of exposed parts can prevent this to a large extent.
Spilled chemicals and solvents must be removed immediately. In particular,
the power plug should be protected from contamination.
Warning
Hot surfaces
The UV lamp, sample vessels and sample holder become very hot dur-
ing operation. The UV lamp can reach a temperature of 900 °C.
Skin contact during and immediately after sample digestion will cause
burns.
Only clean the wet end once it has cooled completely.
