DT Record calibration curve
“DT Record calibration curve” is used to record calibration curves
for the dilution titration calibration technique (with the CVS and
CPVS mode). Dilution titration
Calibration technique is mainly used
to analyze Suppressors in electroplating baths. The calibration
curves recorded with this
Calibration technique are used to de-
termine Suppressor concentrations with the Calibration technique
“DT Suppressors with calibration curve”.
Achtung: A determined calibration curve can only be adopted
automatically if the checkbox Save calibration curves additionally
without date and time on the General tab of the GENERAL SET-
TINGS window is checked.
Determination tab with Calibration technique “DT Record
calibration curve”
The Determination tab of the EDIT WORKING METHOD PARAME-
TERS window contains general specifications for performing the
determination. The parameters displayed depend on the selected
Calibration technique and measurement Technique . With “DT Re-
cord calibration curve” following parameters have to be defined:
Sample identifier [ 32 characters ; "sample" ]
Identification for sample.
Note: The Sample identifier is used for the file na-
me. To make sure that for Suppressor analysis
with 838 Advanced Sample Processor and DT al-
ways the latest calibration file is taken for the cal-
culation, this
Sample identifier must match with
the name of the calibration file defined for the pa-
rameter
Calibration curve on the Determination
tab with calibration "DT Suppressors with calibra-
tion curve".
Example for Sample identifier :
