The titration error in potentiometric precipitation titration
Talanta, 1975The titration error can be calculated with the aid of the value of the buffer index determined at the inflection point of the titration curve when a precipitation titration is followed with an ion-selective electrode. When the precipitate is not formed ideally in the titration (i.e., is not formed under equilibrium conditions) the titration error ...

Talanta, 1972
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.

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 ...

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.

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

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.

Protamine titration is the gold standard method for the measurement of unfractionated heparin (UFH) concentration in plasma. Protamine titration produces reliable and reproducible results; however it is -generally not considered a convenient assay for current clinical management of UFH as it is not readily automated (Olson et al.
