
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 same boat is then moved further into the furnace to determine the TOC
(after removing the TIC) through combustion in the oxygen flow.
6.6 TIC determination with the manual TIC solids module
6.6.1 Preparing the manual TIC solids module and analyzer
The manual TIC solids module only works in conjunction with the C/S module. Here,
the measuring gas is not sucked through the detector with the pump of the basic de-
vice, but is purged with acid in the closed system and transported with the carrier gas
(oxygen) to the detector.
1. Detach the "pump" and "analyte" connection between the multi EA 4000 and the
C/S module. (All other connections can remain as they are).
2. Check the hoses, see hose diagram (Figure 38 p. 60 and Figure 39 p. 61).
3. Connect the manual TIC solids module to the C/S module:

NOTICE
Always interrupt the "pump" connection between the C/S module and the multi EA
4000. Otherwise, phosphoric acid might be inducted into the system and damage the
detectors.
For C/S measurements the "pump" connections must be restored again.
6.6.2 Performing a TIC measurement
Only use dry 50 ml Erlenmeyer flasks with a standard ground joint of NS 29/32 for
analysis purposes.
The sample should be pulverized as finely as possible and homogeneous.
