Analytik Jena multi EA 4000 User Manual

Operation
78 Edition 01/2016 multi EA 4000
− The sampler takes boat 2 with the identical sample from the sample rack and
moves it directly into the hot zone of the furnace. Here it is incinerated in the oxy-
gen flow. The total carbon content (TC) is determined in this way.
− The difference of the two measured values (TC-TIC) is then calculated and issued
as TOC result in the program.
IMPORTANT
During prolonged pauses during measurement the gas supply can be reduced in the mult
i-
Win program saving gas accordingly. However the gas supply must be available again in
time (approx. 10 min) before starting the measurement.
7.5.5 TOC measurement with direct detection
CAUTION
Only use HCl acid to purge the TIC from the sample. Phosphoric acid is not suited for the
direct detection of the TOC.
Perform a measurement as follows:
1. In the acid bottle of the TIC solids module keep 10% hydrochloric acid ready.
2. Switch on the basic device multi EA 4000, the C/S module, the automatic TIC solids
module and 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.
3. Start the multiWin program.
4. 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.
− Activate the E
JECTION RAIL option.
5. Then initialize the system by clicking on [I
NITIALIZE ANALYZER].
6. Load a method (menu item M
ETHOD / METHOD - ACTIVATE) or create a new method
(menu item M
ETHOD / METHOD NEW).
Select the IC/OC parameter.
7. After the run-in time set the following gas flows:
pump
O
2
Ar/O
2
approx. 1.7 l/min
corresponds to
TARGET = 100 ± 5 in the STATUS window
1 l/min 1.5 l/min
The analysis system now has time for conditioning.
If the intake flow differs greatly or changes subsequently, re-adjust it at the "pump"
valve of the multi EA 4000.
