Ganimede N sample preparation
•
Samples that contain substances that react aggressively with Viton, e.g. solvents,
must be diluted.
•
Samples containing particulates must be homogenized with a disintegrator for 30
seconds.
•
Homogenized samples in positions 1 to 27 can be stirred with magnetic rods with the
sample tray for 36 sample containers.
•
The sample containers are suitable for one-time use only.

Load the sample tray
Each sample tray is a sample batch.
If multi-point calibration is to be used, a standard curve with 2–11 measurement points
must be recorded before the measurement series. The device refers to this recorded
curve during measurement operation.
Alternatively, it is possible to work with a two-point calibration. To do so, two standard
solutions are each positioned in positions 33 and 36 for the low and high measurement
range.
For this, load the sample tray as follows:
•
According to the sample batch, the sample tray is loaded with the samples from
position 1.
