12. Confirm the input with the top menu key and close the window.
In the storage locations for STD. CURVE 1, 2 and 3, standard curves, with 2 to 11
measurement points each in the low and high measurement range, are measured and
stored. The device refers to these stored curves if the sample batch is to be processed
after the multi-point calibration.
1. Select standard curves 1, 2 or 3 and the low or high measurement range.
The selected standard curve is opened; standard curves that are already stored can
be modified individually.
2. Select the standard concentration to be changed and confirm the input.
3. Enter the standard concentration with the alphanumeric keys or the connected
keypad and confirm the input.
4. Add further standard measurement points or remove points with the shortcut keys.
5. Open the standard series graphically with the GRAPH shortcut key.
The standard curve can be printed out with Enter.
6. Measure the standard absorbances with the MEASURE shortcut key.
7. Load the sample changer with the desired standard solutions in ascending order from
position 1.
The standard solutions GCZ 100, GCS 050 and GCS 100 with 0.5 mg/L, 30 mg/L and
100 mg/L TN and their dilutions are recommended.

8. Make the analysis unit ready for operation.
9. Switch on the analysis unit and the sample changer.
10. Start the measurements of the standard solutions with the MEASURE shortcut key.
A connection to the analysis unit is established automatically via the IR interface.
11. Select the nitrogen parameter.
The measuring process is started.
Note: The open-loop control unit must not be moved or removed during the transmission
procedure. The whole data transfer is shown on the display.
12. Confirm the input with the top menu key and close the window.
Note: If only one measurement range (high or low) is stored under the standard curve 1, 2 or 3, only
samples of the corresponding measurement range can be measured with this standard curve.
Combinations of different standard curves (e.g. standard curve 1 low and standard curve 2 high) are
not possible.
A rinse of the system with cleaning solution (GCR 100 for Ganimede P and GCR 200 for
Ganimede N) is necessary every working day.
1. Remove the reagent bottles and close the bottles tightly with the corresponding
color-marked lids.
2. Store reagents in the refrigerator.
Note: The reagents can be kept for a maximum of seven days after opening.
3. Connect the bottles with cleaning solutions to the corresponding lid under
consideration of the color markings.
