This chapter discusses the titration system.
The optimum sequential injection titration system was investigated for the effect of interferences, precision, and sample frequency.
The titration system allowed the determination of ascorbic acid in pharmaceutical formulations with concentrations ranging from 7.5 to 15.0 mmol l−1.
The amount of surface hydroxyl groups and their acid base properties were characterized by batch-back titration [24], using a PC-controlled titration system (751 GPD Titrino with software Vesuv 3.0, Metrohm AG, Herisau, Switzerland).
Constant composition was maintained in the reactor through the use of an automated titration system; a decrease in solution pH due to calcium carbonate precipitation triggered the addition of solutions (at a rate of 10 μl/s) containing the cation and anion in equal amounts until the reactor pH returned to the target value of 8.5.
Purified human salivary protein was analyzed by an automated titration system (Mettler-Toledo DL53, and the Software Lab X pro V 2.10.000) with the same titration parameters except that only 50 µl of acid were added per step.
Magnetite was synthesized through the coprecipitation method controlled by a titration system (Metrohm, 776 Dosimat and 719 S Titrino).
In this titration system, the ratio of the total heat of mixing and dilution to all the evolved heat was decreased below 0.1.
The average water content in the final bottles of the FD material was 6.1 ± 0.7%% (m/ m) as determined using volumetric Karl Fischer titration system (Metrohm, Herisau, CH).
Equilibrium titration employed a self-developed titration system (GIMET1), 665 Dosimat (Metrohm) burets, a magnetic stirrer, a high performance potentiometer, a pH electrode (OP-0808P Radelkis), and an IBM PS/1 PC.
