Populate the autosampler. Use the
and
buttons to move the sample
rack to the desired position.
Click on in the sequence row to release it for analysis. All sequence rows can
be released by clicking on the
button.
Sequence rows released for analysis have a green fill.

window opens.
The boat pick-up picks up a boat from the sample rack and places it onto the
ceramic hook.
The ceramic hook moves the boat into the TIC reactor. As soon as the boat has
reached the position under the ceramic cannula, the acid addition starts auto-
matically. During the slow boat feed acid is added to the entire sample.
The measuring gas from the purged TIC is passed via the measuring gas drying
and cleaning of the automatic TIC solids module to the detector in the C/S
module. The oxygen supply at the inlet of the TIC reactor prevents measuring
gas from escaping through the open inlet.

CAUTION
During autosampler operation 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.
This is the method recommended here.
1.
Fill the acid bottle of the TIC solids module with 40% orthophosphoric acid.
2.
Switch on the basic device multi EA 4000, the C/S module, the automatic TIC solids
module and 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.
The status lights at the front of the devices illuminate.
Do not switch any Cl module present.
3.
Start the multiWin program.
4.
Change between the various analyzer modules. To do so, first activate the sensors:
