8. Weigh the sample on ceramic boat.
9. Start the measurement by clicking on [S
TART MEASUREMENT].
10. Create or select an analysis group for storing the measuring data.
11. Create an analysis sequence.
− Add the desired number of samples to the sample table with .
− Enter the following data:
Column Description
SAMPLE POSITION Position of the sample on the sample rack.
The sample rack assignment may only take place
with ascending position numbers. However, it need
not be without gaps.
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
OAT BLANK DETERMINATION
NOMINAL VALUE Target concentration for calibration standards or AQS
standard
Entry of the weighted sample
− Populate the sampler. Use the buttons and to move the sample rack into
the desired position.
− 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.
12. Click on [START MEASUREMENT].
Note: During measurements with manual sample feed an additional input window ap-
pears before each measurement start to enter the weighted sample.
The analyzer starts processing the analysis sequence. The MEASUREMENT -
ANALYSIS
window opens.
− The boat pick-up takes a boat from the sample rack and places it onto the ceramic
hook.
− The ceramic hook moves the boat into the TIC reactor. As soon as the boat has
reached the position below the ceramic cannula, the acid is added automatically.
During the slow boat advance the entire sample is mixed with acid.
− The measuring gas with 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 detect the TOC (after re-
moving the TIC) by incineration in the oxygen flow.
