Titration errors in acid-base titrations
Microchemical Journal, 1990Abstract An attempt to offer a unified treatment of titration error in acid-base titrations is given in this paper. Special attention has been paid to the relationships between the titration error and the maximum sharpness index for various kinds of acid-base titrations.

Evaluation of Automatic Potentiometric Titrator in Nonaqueous Titrations
Journal of Pharmaceutical Sciences, 1966A procedure is reported for the evaluation of the behavior of an automatic recording titrator in nonaqueous titrations and is applied to an instrument composed of commercially available units. First, the behavior of the purely instrumental features was determined and the experimental errors were compared with calculated maximum anticipated relative ...

End-point detection in some precipitation titrations is achieved by measurement of the surface tension between mercury and the solution ("stalagmometric" titration). The drop-time of a polarographic dropping mercury electrode in open circuit is plotted against volume of surface-active titrant added, and shows a break or a peak at the end-point.

Titration curves of compleximetric back-titrations
Analytica Chimica Acta, 1970Abstract Conditions are derived for sharp end-points in compleximetric back-titrations of mixtures of metals, by means of potentiometric indication of one of the metals of the mixture. Some applications are given for the determination of Cu, Zn, Bi and Ni with EDTA as the ligand and thorium(IV) as the titrant.

Systematic titration errors in redox titrations
Analytica Chimica Acta, 1969Abstract Exact and approximate expressions have been derived for the calculation of systematic titration errors in redox titrations. Some numerical examples are calculated, and it is shown that the proposed expressions yield higher values for the titration errors than are given by some recently suggested expressions.

Improved linear titration plots for weak-acid titrations
Talanta, 1974Linear titration plot functions are derived for the following types of titration: weak monobasic acid-strong base, weak dibasic acid-strong base weak acid-weak base. These functions are compared with the corresponding Gran functions, where possible, and the effects of the following sources of error are discussed: the neglect of activity coefficients ...

Current Protocols in Protein Science, 1999
AbstractIsothermal titration calorimetry (ITC) is perhaps the most rigorous commercially available method for characterizing protein‐ligand interactions. In this method, interactions are detected by the intrinsic heat (binding enthalpy) change of the reaction. The technique is applicable to native, unmodified proteins in solution. This is important for

Publisher Summary This chapter deals with the classical volumetric titrimetry. The concentration of an analyte in a solution is determined by measuring the volume of a reagent of known concentration that is needed to react with that analyte. In classical titrimetric analyses, the immediate goal is to find the endpoint volume of the reagent, R, as an ...

This chapter examines in detail the necessary practical skills needed to facilitate the development and sustainability of ELISAs. Basic methodologies to set up all systems are discussed so that the reader can both investigate the possibilities of tests using his or her reagents and use with confidence the reagents obtained from other sources.
