7.3 Carbon detection after pyrolysis
7.3.1 Preparing the multi EA 4000 and C/S module
WARNING! ELECTRIC SHOCK!
Lethal voltages may occur in the combustion furnace. The combustion tube is part of the
cover of live components.
Therefore, only
switch on the analyzer with the combustion tube inserted! For conversion
and maintenance activities at the combustion tube or combustion furnace, always switch off
the analyzer from the mains switch and disconnect the multi EA 4000 by removing the mains
pl
ug from the mains network.
For the detection of carbon after pyrolysis the multi EA 4000 must be equipped with the op-
tional pyrolysis mode.
1. Check the electric and pneumatic connections in accordance with section "Installing the
multi EA 4000 C/S" p. 122.Check in particular the argon connection at the multi EA
4000.
2. Attach an exhaust device above the gas airlock on the right-hand side of the EA 4000 to
catch and remove the escaping pyrolysis gases.
3. Perform all the other modifications of the analyzer as described in section "Preparing
the multi EA 4000 and C/S module" p. 52:
− Install the ceramic tube with the gas airlock in the combustion furnace.
− Make sure that the copper and brass wool in the halogen trap are not discolored.
− Install the autosampler.
7.3.2 Performing the carbon detection after pyrolysis
1. Switch on the basic device multi EA 4000, the C/S module and, where applicable, the
FPG 48 from the main switch.

The status lamps at the device front panels illuminate.
Note: Do not switch on any Cl module present. The automatic TIC solids module must
not be switched on.
2. Start the multiWin program.
3. Change between the different analyzer modules, first activating the sensors:
− Select the menu item D
EVICE / DEVICE - EDIT.
− Activate the E
LEMENTS to be analyzed.
− If both carbon/sulfur and chlorine have been activated, click on C
ERAMIC TUBE CS in
the list C
OMBUSTION TUBE.
− As S
TATES enable the option SOLID.
4. Then initialize the system by clicking on [I
NITIALIZE ANALYZER].
5. Load a method (menu item M
ETHOD / METHOD - ACTIVATE) or create a new method
(menu item M
ETHOD / METHOD- NEW).
− Select the parameter "EC/TC" to detect the carbon after pyrolysis.
− Recommended parameters for the method configuration (tab P
ROCESS):
