Titrando, 855
Range
0.01 ... 166.00 mL/min
Default value 0.25 (50 µL/min), 0.75 (100 µL/min), 2.00
(500 µL/min) mL/min
Titrino
Range
0.01 ... 150.00 mL/min
Default value 0.25 (50 µL/min), 0.75 (100 µL/min), 2.00
(500 µL/min) mL/min
Min. rate
Rate at which dosing is carried out at the very beginning of the titration
and in the Control range at the end of the titration. The smaller the
selected minimum rate, the longer it takes until the control point is
reached for the first time. The following rule of thumb should be observed
for maintaining the Min. rate in order to achieve as constant (regular) a
dosing at the control point as possible: Min. rate in µL/min = expected
reaction rate in µL/min/10.
Range 0.01 ... 9999.00 µL/min
Default value 10.00 (50 µL/min), 20.00 (100 µL/min), 40.00
(500 µL/min) µL/min
Note
Outside the control range the dosing rate is mainly characterized by the
Max. rate. The parameters Max. Rate und Dynamics pH should be
optimized together in such a way that the titration does not overshoot
too much when the control point is reached. The control range should
be selected in such a way that the measured value remains within this
range when dosing stops. A slightly larger control range should be
defined for slow reactions (e.g. pH = 3). The nominal value is often set
with a SET pretitration before the substrate is added. This means that
the STAT titration can be started with a small deviation from the control
point. Within the control range the dosing rate is mainly characterized
by the Min. rate.
