optimal
Parameter set for all standard titrations; optimized for the most frequent
applications.
fast
For less critical, fast titrations.
User
Editing the individual titration parameters which affect the titration rate.
Control
Note
Will be displayed only if the User option is selected in the Titration
rate list box.
Dynamics
The control range is entered as distance to the endpoint. Within the control
range, bromine will be generated in steps which are controlled by the Min-
imum rate. The larger the control range, the slower the titration. Outside
the control range, bromine will be generated continuously with Maximum
rate.
The standard control parameters are optimal for most applications and
should not be modified. If you nevertheless need to modify the control
parameters for special reagents and/or samples take care that the polariza-
tion current of the indicator electrode (I(pol)), the endpoint and the control
range are linked to each other.
Range 0.1 ... 1250.0 mV
Default value 400.0 mV
Max. rate
Maximum rate with which bromine is generated outside the Control
range.
Range 10.0 ... 19876.0 µg/min
Default value 500.0 (slow), 1000.0 (optimal), 2000.0
(fast) µg/min
Selection maximum
Default value maximum
Min. rate
This parameter defines the minimum rate with which bromine is generated
inside the Control range. The smaller the rate the slower the titration and
the higher the accuracy.
