3.2.4 TIC-module Operation procedure
1. Place the empty glass flask (6) on the balance.
2. Press tare.
3. Put the sample into the flask and enter the weight into the analyzer (F4-
button). When powder sample sticks in the flask neck, add 2 ml of water (but
don't transfer the weight of the water!)
4. Place a magnetic stirrer into the flask and attach the flask
to the distributor (3).
5. Raise the adjustable platform to support the flask. Check, and if necessary,
readjust the flask so that its bottom lies flat on the heated platform.
6. Switch to TIC-mode with the TIC/TC toggle (13).
7. Start analysis (F5 or click START).
8. Inject acid in two or three doses, when the word “Analyzing” appears.
9. When all the CO2 has been released from the sample, the analyzer's signal
will return to the baseline level and the analysis will be terminated.
10. switch to TC-mode with the TIC/TC toggle (13).
NOTICE
The rotary speed of the stirrer should be kept low. The rotary speed and the acid
dosing should be done in a way to avoid sample particles being pushed up and
stick on the inner glass surface.
The heater must be switched on. Do not allow boiling or evaporation of the solution
in the flask!
