12.
Slice the white PTFE ring onto the end of the TIC reactor.
13.
Position the sampler FPG 48 and retrofit the boat storage
(
→
see section "Installing and adjusting the autosampler
Move the sampler towards the TIC solids module. The TIC
reactor with the PTFE ring will rest on the edge of the sam-
pler.
A gap of 2-4 mm must remain between the TIC reactor and
the sampler to prevent tension from the thermal expansion
of the ceramic tube.
14.
Align the sampler until the ceramic boat can just be moved into the reactor and
further into the furnace for TOC measurements.
15.
Provide a container for the used ceramic boats to the right of the FPG 48 under the
ejection rail.
6.5.2
Reagents required
The following reagents are required for TIC determination:
40% orthophosphoric acid (for the recommended differential method)
10% hydrochloric acid for TOC determination (for the direct method)
6.5.3
TIC determination with the automatic TIC solids module
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.
1.
Fill the acid bottle of the TIC solids module with orthophosphoric acid.
2.
Switch on the basic device multi EA 4000, the C/S module, the automatic TIC solids
module and the sampler 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:
