General information
To avoid the risk of electrocution, make sure the instrument is disconnected from the
power source before changing the lamps.
2.2 Product overview
2.2.1 Product overview of the Ganimede P
In combination with the ready-to-use GaniChem P GCA 100 reagent kit, the Ganimede P
enables a rapid and automated serial analysis of PO
4
and PO
4
-P as total phosphate or
orthophosphate in accordance with DIN EN 1189 of December 1996.
The digestion of the total phosphate takes place as high-temperature digestion.
The phosphate content is determined as phosphorus molybdenum blue at 880 nm.
2.2.2 Product overview of the Ganimede N
In combination with the ready-to-use GaniChem N GCA 200 reagent kit, the Ganimede N
enables a quick and automated serial analysis of inorganically and organically bound
nitrogen in aqueous samples in accordance with DIN EN ISO 11 905-1.
Inorganically and organically bound nitrogen is oxidized to nitrate with peroxodisulfate by
means of alkaline digestion at 150 °C and 8 bar.
The nitrate content is photometrically measured by means of UV self-absorption in a
differential measurement at 210 nm and 228 nm.
C A U T I O N
Health hazard caused by ozone.
Hazardous levels of ozone can be generated when the UV lamp is not cooled.
WA R N I N G
Health risk due to UV light.
UV light can cause irritation to the eyes and skin. Protect eyes and skin from direct exposure to
