Gas supply control
The composition of the gas mixture for optimum gas digestion is controlled via the flow
management system (FMS).
4.1.2.4 Combustion system
A resistance-heated combustion furnace for digestion temperatures of 700 to 1100 °C is
used in the basic module. Digestion with the multi-purpose combustion tube is per-
formed at temperatures of 950 °C
or 1000 to 1100 °C, depending on the application.
The double furnace device can be switched to the required operating mode quickly via
the tilt device.
Figure15 Combustion furnace in the vertical and horizontal operating mode
A multi-purpose combustion tube used for all standard applications, both in vertical or
horizontal operation mode, is installed in the combustion furnace. The combustion tube
is made of quartz glass. The auto-protection assembly group connects the combustion
tube to the measuring gas dryer or the further path of the measuring gas.
