6 Measurement of a Sample
Solution
6.1 Series
Measurement
With OSMOMAT auto, up to 20 samples can be measured and saved fully automatically in one
procedure.
Position 0 on the sample holder is reserved for internal system initialization.
It must be filled with
distilled water for every series measurement!
■
Filling the Sample Holder
Position
0
with
distilled water
Positions
1
through
20
: can be filled as desired. For example, every second or third position
can be filled.
When filling the sample holder, ensure that position 0 is always filled with a measuring
vessel with distilled water. If position 0 is not filled, there is no measured value for the
first sample!
Be sure to identify samples uniquely.
The sample cover is then placed on the sample holder to prevent premature evaporation of the
samples.
The sample cover reduces the risk of premature evaporation of the samples. However,
it does not protect the samples from leakage.
Incorrect measured values due to evaporation.
Conduct series of tests so that you can adjust your method of working with the unit to
the environmental conditions.
Determine the acceptable time between sample preparation and sample measurement.
