Slowly adjust the stirrer to stage 5. The sample must not be spun against the
wall of the flask. Jolting or rapid movement of the stirrer must therefore always
be avoided.
Add 2 ml acid evenly 1-3 times (dependent on the concentration and sample
volume).
Then close the valve in the metering pump stop cock.
Since the release of CO
2
is also dependent on the metering speed and the stirring
speed of the stirrer magnet, always ensure the same cycle and the same speeds are
used in each measurement.
The analyzer starts processing the analysis sequence. The M

window opens.
19.
After completing the measurement stop the magnetic stirrer and open the flask:
Detach the TIC head with a twisting motion. Move the arm of the stand-up, swivel
it back and lock it in this position.
20.
Clean and dry the flask.
21.
Connect a dry Erlenmeyer flask to the TIC head during breaks in measurements.
This maintains the oxygen flush (conditioning) and the dry gas flow frees the hose
system of moisture residue.
22.
Keep the heating plate at a constant temperature. Only switch off the thermostat
during longer measuring breaks.
