Standard addition for brighteners” following parameters have to be
defined:
Sample identifier [ 32 characters ; "sample" ]
Identification for sample. The Sample identifier is
used for the file name.
Volume production bath (mL) [> 0 mL ; 10 mL]
The volume of sample bath solution added (see
Production bath solution, section 6.4).
Cell volume (mL) [ > 0 mL ; 10 mL ]
Total volume of solution (“Production bath soluti-
on” + (if necessary) auxiliary solution) in the mea-
suring vessel at the start of the determination. The
sample concentrations Conc. calculated refers to
this cell volume.
The used "Intercept value" can be defined in 2 ways:
Intercept value (mC) [> 0 ; 0 ] [± ; 0 ]
Read the previously determined "Intercept value"
out of the report and enter it here.
Intercept determination
Define the Intercept-file (the file in which the de-
termination of the "Intercept value" was(will be)
saved). The method then reads out the value for
the calculation automatically. Use the button
to search for the file.
Note: To make sure that always the latest inter-
cept file is taken for the calculation when analyz-
ing Brightener with the 838 Advanced Sample
Processor and "LAT", the name of the intercept
file defined for Intercept determination, must
match with the parameter
Sample identifier on the
Determination tab with Calibration technique "LAT
Record intercept value".
Example for Intercept determination:
C:\User XYZ\Data\Intercept.dth
Note: To make sure that always the latest inter-
cept file is taken for the calculation when analy-
zing Brightener with the 838 Advanced Sample
Processor and "LAT", the path of the intercept file
defined for Intercept determination, must match
with the path defined for the parameter Data fol-
