} Insert approx. 500mg of quartz glass wool in the combustion tube. Carefully press
the glass wool down to a height of approx. 1cm with a glass rod. Do not press it
down too tightly.
} Carefully pour 16g of platinum catalyst onto the quartz wool (fill height approx
4cm).
} Cover the catalyst completely with approx 250mg of quartz glass wool. Carefully
tamp down the quartz wool.
} Fill approx. 10g of ground quartz glass into the combustion tube (fill height approx.
2cm).
} Cover the ground quartz glass with a piece of high temperature fiber mat (HT mat)
(layer height approx 1cm).
} Close the filled TOC combustion tube with septum and screw cap and reinstall it in
the furnace in reverse order.
} Check the analysis system for leaks.

NOTICE
The catalyst may emit gas during first heating, this can be seen as mist formation in the
TIC reactor.
¡ Allow the catalyst to normalize during first heating for approx. 30min until mist no
longer forms. Disconnect the gas path between the TIC reactor and the water traps
for this.
