How to measure different samples
Note
The sample tray must be assembled outside of the instrument.
How to measure cuvettes (powder or liquid)
Caution! Fire hazard!
When using flammable samples, there is an increased risk of fire.
Always measure gaseous, highly volatile or flammable samples separately.
This will limit the amount of samples to an amount that will prevent the
spread of fire.
Notice! Damage to instrument!
Escaping liquids can damage the instrument.
When measuring liquids, always use the "liquid protect cup" with an additional
protective film.
When measuring liquid samples, the maximum permitted number of cuvettes
on one sample tray is limited to four.
Observe the following instructions when inserting the samples:
Leave the filled cuvettes outside of the sample chamber for approx. 3 minutes
and then check them for tightness and ensure the film is undamaged.
If the film is crinkled, the sample with this film must not be measured. In
this case, the sample must be prepared again, using a new cuvette and
film.
If the film is damaged inside the sample chamber, there is an indentation in the
chamber (discharge reservoir) in which the sample material is collected.
Therefore, only measure the liquid and powdery samples while they are in the
following trade positions:
Standard tray (12 positions à 40 mm): Position 4 to position 9
Rotation tray (8 positions à 40 mm): Position 3 to position 6
Tray for small samples (25 positions à 20 mm): Position 7 to position 20
For cuvettes, a filling height of 10 mm it is recommended. Some cuvettes use a
level indicator to display the filling height. To arrive at the correct analysis, in
addition to the filling height, the weighted portion of the sample (or the density, if
known) must be determined and entered into the software.
