7.6 TIC detection with the manual TIC solids
module
7.6.1 Prepare 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 pumped through the detector with the pump of the basic device, but
purged in the sealed system with acid and passed with the carrier gas (oxygen) to the detec-
tor.
1. Disconnect the connection "pump" and "analyte" between the multi EA 4000 and the
C/S module. (All other connection can remain connected).
2. Check the hoses in accordance with the hose diagram (see Fig. 42 p. 135 and Fig. 43
p. 136).
3. Connect the manual TIC solids module to the C/S module:
