Installation
3.2.2 Switch-on of the open-loop control unit
The open-loop control unit is switched on with the power switch on the left-hand side of the
housing.
The open-loop control unit is ready for operation after the manufacture's logo is shown.
The charge status of the battery, as well as the date and time, are shown on the display
next to the main menu.
Upon delivery, the open-loop control unit is set to the correct national language, date and
time. If these values are not entirely correct, they can be changed in the menu option
OPTIONS, DATE/TIME and OPTIONS, LANGUAGE.
The main menu options are accessed with the adjacent shortcut keys.
3.3 Reagents
3.3.1 Reagents for Ganimede P
The GCA 100 reagents for the automated orthophosphate and total phosphate
determination are designed for 100 determinations. The principle of the reaction complies
with DIN EN 1189 of December 1996.
Phosphate ions react in acid solution with molybdate and antimony ions to form an
antimony–phosphomolybdate complex that is reduced to phosphorus molybdenum blue
by means of ascorbic acid.
The opened solutions can be kept for seven days at room temperature.
Prepare the reagents according to the work instructions enclosed in the reagent
packaging.

The Ganimede P and the ready-to-use GaniChem-P GCA 100 reagent kit are optimally adapted
for each another. The use of third-party chemicals can result in the impairment of the results and
the whole system.
The guarantee claim only remains valid with the use of GaniChem-P GCA 100.
