broken
Tube cracks in lengthwise
direction.
The sampler base is fixed
with screws while the quartz
pyrolysis tube is not inserted
to the dead end of the
furnace.
Fixed the upper part in the state that a quartz
pyrolysis tube was not inserted in properly to
the depths and might tighten up ITF union. To
see an instruction manual, please confirm
whether a quartz pyrolysis tube is attached
definitely.

Repair needed.
Temperature unstable at low
temperatures (eg. 100ºC or
below)
ITF temperature may be too
high
Set ITF temperature control to Auto. (In Auto
