NOTICE
Risk of detector damage
The catalyst can emit gas during initial heating, this can be seen as mist formation in the
TIC condensate container.
¡
Allow the catalyst to burn out during initial heating for approximately 30 min at op-
erating temperature.
¡
During this, interrupt the gas flow at the water traps on the front side to protect the
detector from the gases.
Filling the combustion tube, for normal samples
}
For filling, fix the combustion tube in a stand.
}
Fill quartz glass wool (1) into the combustion tube approx. 1 cm high,
carefully press it down with a glass rod and press it into place.
The glass wool holds back the catalyst. Ensure that no catalyst can get
into the gas pathway. Also, do not pack the glass wool too tightly!
}
Carefully stack platinum catalyst (2) onto the quartz glass wool approx.
4 cm high.
}
Roll up the HT mat (3) from the narrow side.
The roll must have a diameter of approx. 13 mm and a height of 2 cm to
slide into the combustion tube easily.
}
Insert the rolled-up HT mat into the combustion tube and push it down
with a glass rod until the catalyst is covered.
}
Only press the mat down lightly onto the catalyst.
The recommended operating temperature for this filling is 800 °C.
