7.5.3 Filling the combustion tube
CAUTION
Alkaline salts (hand perspiration) causes crystallization in the quartz glass when heating
combustion tubes in the combustion furnace. This shortens the servi
ce life of the
combustion tube.
Where possible do not touch the cleaned combustions tube with your hands for filling.
Wear protective gloves during the filling of the combustion tube. Wipe any finger marks
on the combustion tube with a cloth wetted with pure alcoh
ol.
Only fill fully dried combustion tubes. If necessary, dry the combustion tube before
filling.
1
Quartz wool, approx. 1 cm
2
Platinum catalyst, approx.
4 cm
3
rolled-up HT mat, approx.
2 cm high
You can fixate the combustion tube on a tripod for
filling. Fill the combustion tube in accordance with
the following instruction from the bottom up:
1.
Insert the quartz glass wool approx. 1 cm thick
into the combustion
tube, carefully push it down
with a glass rod and compact it.
Note
: Don't press too tight! The quartz glass wool is
used to retain the catalyst. Make sure that no
catalyst can enter the subsequent gas path.
2.
Place the platinum catalyst for multi N/C
carefully onto the quartz glass wool (approx. 4
cm high).
3.
Roll up the high temperature fiber mat (HT mat)
of the narrow side. The roll must have a
diameter of about 13 mm and a height of 2 cm,
so it can easily slide into the combustion tube.
Insert the rolled HT mat in the combustion tube
and slide the HT mat with a glass rod far enough
that the catalyst is covered. Press the mat only
slightly onto the catalyst.
The recommended work temperature for this filling
is 800 °C.
