Note: A determined "Intercept value" can only be adopted auto-
matically, if the checkbox Save calibration curves additionally with-
out date and time
on the General tab of the GENERAL SETTINGS
window is checked.
Determination tab with Calibration technique “LAT Record
intercept value”
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 “LAT Re-
cord intercept value” following parameters have to be defined:
Sample identifier [ 32 characters ; "sample" ]
Identification for sample.
Note: The sample identification is used for the file
name. 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", this
Sample identifier must
match with the name of the intercept file defined
for the parameter Intercept determination on the
Determination tab with Calibration technique
"LAT".
Example for Sample identifier: Intercept
Volume intercept solution (mL) [> 0 mL ; 10 mL]
The volume of intercept solution added (see
Intercept solution, section 6.4).
Cell volume (mL) [ > 0 mL ; 10 mL ]
Shows the volume given for Volume intercept so-
lution
.
Initial electrode conditioning (see Initial electrode conditioning,
section 6.3)
Check the checkbox to use conditioning.
No. of conditioning measurements [ 1...100 ; 1 ]
Number of replications of conditioning measure-
ments. The “total number of conditioning mea-
surements” is the No. of conditioning measure-
ments
multiplied with the number of Save last ..
sweeps
(Voltammetric tab). “Total number of con-
ditioning measurements” must not exceed 100.
or Auto Std.dev (%)[ >0.1 ; 1 ]
Define until which „Std.dev.“ the conditioning is
continued. The „Std.dev.“ is calculated from all sa-
ved sweeps of the last two “conditioning mea-
surements”.
