12. Place the TIC head onto the flask. Rotate the flask and TIC head and press both slightly
against each other. The boat connection must be gas-tight to prevent measuring gas
from escaping.
13. Start the measurement by clicking on [S
TART MEASUREMENT].
14. Create or select an analysis group for storing the measuring data.
15. Create an analysis sequence.
− Add the desired number of samples to the sample table with .
− Enter the following data:
Column Description
NAME Sample ID
With an automatic sample ID can be generated.
ANALYSIS TYPE Selection of the analysis type (SAMPLE, DAILY FACTOR,
CALIBRATION MEASUREMENT, AQA MEASUREMENT or
BOAT BLANK DETERMINATION)
NOMINAL VALUE Target concentration for calibration standards or AQA
standard
OPERANDS Entry of the weighted sample
− Click on in the sequence row to release it for analysis. All sequence rows can
be released with the button .

Sequence rows released for analysis have a green fill.
16. Click on [START MEASUREMENT].
17. Enter the weighted sample in [mg].
18. Wait for the ready message of the analyzer.
Before the measurement the analyzer must have been conditioned with oxygen. To this
end the air must have been forced out of the flask and hose system and only oxygen
must reach the detector. Dependent on the flask size this can take up to 2 min.
19. After the message "P
LEASE PRESS 'OK' TO START INTEGRATION AND THEN ADD ACID!." click
on [OK].
Initially meter 2 ml phosphoric acid.
Slowly set the stirrer to stage 5. The sample must not be flung against the flask wall.
Jerky or rapid movements of the stirrer should therefore be avoided at all times.
Add 2 ml acid each evenly 1 - 3 times (dependent on the concentration and sample vol-
ume).
IMPORTANT
Since the release of
the CO
2
also depends on the metering speed and the stirring speed of
the stirring magnet, always keep to the same cycle and the same speeds for each mea
s-
urement.

The analyzer starts processing the analysis sequence. The MEASUREMENT
ANALYSIS window opens.
20. After completing the measurement switch off the stirring magnet and open the flask:
Release the TIC head with a rotary movement. Move the tripod arm upwards, tilt it back
and lock it in this position.
21. Clean and dry the flask.
