CAUTION
When working with quartz wool avoid the creation of dust! Inhaled dust might cause
irritation to respiratory tracts.
NOTICE
Alkaline salts (hand perspiration) cause crystallizations in the quartz glass when
heating the combustion furnace which reduce the service life of the combustion tube.
Do not touch the combustion tube with your bare hands during re-installation. Wear
protective gloves. If necessary, clean the combustion tube externally before installing it
in the combustion furnace (e.g. by wiping it with moist cellulose).
1.
Exit the multiWin control software and allow the analyzer to cool down.
2.
Switch off the multi X 2500 and the chlorine module and pull the mains plugs from
the power outlet. Cut the gas supply.
3.
Remove the top cover or the multi X 2500 or the sample introduction module and
open the front doors.
4.
Detach the connection hose and the spherical joint (1) from
the sulfuric acid container (vertical).
5.
Detach the forked clamp (2) between the sulfuric acid
container and the combustion tube.
6.
Carefully remove the sulfuric acid container from the drip tray
and empty it. Observe the regulations for handling
concentrated sulfuric acid!
7.
Remove the oxygen sluice (1). Pull the angled adapter (2) off
the oxygen sluice.
8.
Remove the heat bridge from the analyzer.
9.
Pull the open combustion tube upwards to remove it from
the furnace.
10.
Check the combustion tube for excessive crystallization,
cracks and blow-outs. Only reuse intact combustion tubes.
11.
Remove the quartz wool plug from the combustion tube and
check its condition.
12.
Thoroughly rinse the empty combustion tube with ultrapure
water and dry it well.
