Load Sample Filter
The sample filters come as a sheet of alumina /
silica (Al
2
O
3
96%/SiO2 4%) Non-Woven Fabric.
A small disc of this fabric is needed to place the
sample on. The following procedure must be
used to load the filter into the Sample Holder.
Warning
: The above mater ial is har mful by
inhalation and when in contact with skin. Possi-
ble risk of irreversible effects. Wear suitable
protective clothing. Wear suitable gloves, eye/
face protection or work in a fume cupboard. This
material is NON-CARCINOGENIC.
Important Note Before Heating Sample:
The
Alumina/Silica Fabric filter on which the sample
is loaded should be heated up to 600ºC before
doing a sample run. Either heat the fabric in an
autoclave or using the CCR1000. Remove the lid
window and run gas through the stage during the
heating phase. This is so that any dust or debris
in the stage or fabric filter is burned off and car-
ried away before start of experiment.
Turn the Sample Holder upside down and with a
forefinger and thumb gently rest it over the alu-
mina/silica fabric (1). Once the sample holder is
in position, apply a very light force and rotate the
sample holder into the alumina/silica Non-Woven
Fabric. This will cut the fabric to fit the sample
holder.
Gently lift the sample holder away from the fab-
ric. The filter will now be the perfect size for the
sample holder.
The filter is not yet low enough in the sample
holder and needs to be pressed into position. This
can be achieved by the using the Filter Load/
Removal Tool (2).
The filter should be in the sample holder and
ready to be pressed into position as shown above.
Make sure that the tool is round the correct way to
press the filter into the sample holder.
Note: To remove the filter, the tool can be used to
push it out of the sample holder. Balance the tool
on a flat surface so that the smaller diameter of
the tool is protruding upwards. Hold the sample
holder over the tool (the Filter Load/Removal
Tool can be supported by hand if required). Gen-
tly lower the sample holder over the filter load/
removal tool.
