Operation
multi EA 4000 Version 01.16 77
The analysis system now has time for conditioning.
If the intake flow differs greatly or changes subsequently, re-adjust it at the "pump"
valve of the multi EA 4000.
8. Weigh the sample on 2 ceramic boats.
Caution:
The weighted sample on boat 1 for the TIC detection must be max. 50 mg. Cover the
sample with some annealed quartz sand. The quartz sand improves the wetting of the
sample with acid.
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 ascend-
ing 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 BOAT BLANK
DETERMINATION
)
NOMINAL VALUE Target concentration for calibration standards or AQA standard
OPERANDS 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 appears be-
fore 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 boat 1 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.
− Boat 1 is then pulled out of the TIC reactor and deposited on the ejection rail.
