Determination of carbon after pyrolysis
6.3.1
Preparing the multi EA 4000 and C/S module
CAUTION
With pyrolysis volatile carbon compounds escape from the multi EA 4000. Attach an
extraction pipe close to the furnace inlet and ensure that the pyrolysis gas is extracted.
1.
Check the electrical connections and hose connections in accordance with section
"Positioning the multi EA 4000 C/S" p. 49. Check in particular the argon connection
at the multi EA 4000.
2.
Fit an extraction pipe on the right hand side of the multi EA 4000 to remove the
pyrolysis gases.
3.
Prepare the analyzer as described in section "Preparing the multi EA 4000 and C/S
module" p. 71:
Mount the ceramic tube with gas sluice and dust trap in the combustion fur-
nace.
Make sure that the drying tube is filled and the copper and brass wool in the
halide trap is not discolored.
4.
Position the sampler FPG 48 (
→
see section "Connecting and using the au-
tosampler" p. 62).
6.3.2
Performing the determination of carbon after pyrolysis
CAUTION
During the operation of the sampler and the manual sample feed there is a risk of
burns at the hot boat and ceramic hook! After pulling out of the furnace the boat and
hook remain hot for a long time.
CAUTION
Crushing hazard at the autosampler! The autosampler arm, the gripper and the boat
carousel move during activation and initialization and measurement operation. Keep
an adequate distance to avoid having your hands crushed.
When filling the autosampler: Only open the cover when the boat carousel is no longer
moving.
NOTICE
Danger of damage to furnace! To not constantly work with furnace temperatures be-
low 1000 °C. Where possible limit the operating period of pyrolysis measurements
(with T = 850 °C).
1.
Switch on the basic device multi EA 4000, the C/S module and, where applicable,
the FPG 48. Make sure to switch on the basic device both from the mains switch at
the rear and the On/Off switch at the front.
