TOC measurement using direct determination
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.
NOTICE
For the TOC measurement with the automatic TIC solids module the differential
method is preferred. In the direct method the combustion tube, the halide trap and the
detectors are loaded with acid, leading to wear.
Only use HCl acid to purge the TIC from the sample. Phosphoric acid is unsuitable for
the direct determination of the TOC.
Perform a measurement as follows:
1.
Fill the acid bottle with 10% hydrochloric 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:
