Analytica Chimica Acta, 1959
Abstract A technique of arbitrary standard weight titrimetric analysis has been proposed for realising the ultimate degree of mechanical precision of which titrimetric processes are capable, and has been applied to reactions and methods of end-point location which are particularly favourable.

Publisher Summary This chapter discusses the applications and the theory of thermal titrimetry. For thermal titrimetry, a concentrated reagent, B, is added to the material, A, at a constant rate. The heat change generated by the reaction is recorded as a function of time or concentration of B added.

Full‐scale automatic titrimetry. II
Journal of Applied Chemistry, 1960AbstractAs a result of practical experience, modifications have been made to the apparatus for full‐scale automatic titrimetry previously described.1 These modifications involve the titrant injection system, the pH or e.m.f. measuring system, the recording apparatus and the titration assembly.

Indirect determination of nitroglycerine by biamperometric titrimetry
Talanta, 1977A procedure is described for the determination of nitroglycerine in propellant samples by biamperometric titrimetry. The method is simple, avoids the use of expensive instruments, and is free from interferences other than those occurring in the classical techniques. The accuracy and precision are equal to those of existing methods.

HIGH-PRECISION VOLUME TITRIMETRY
Canadian Journal of Chemistry, 1962Ways in which the ultimate limit of volume titrimetry may be reached are analyzed: the most suitable approach, based essentially upon the use of a bulb burette, allows, in theory, a mechanical precision better than that of the best weight techniques to be obtained, and the various factors influencing this precision are detailed.

Indirect Determination of Sulfate by Nonaqueous Titrimetry
Analytical Chemistry, 1961A method was developed for the rapid determination of sulfate in the presence of ions such as uranyl and ferric, which interfere in most conventional methods. Sulfate was precipitated by the addition of excess barium acetate. The excess barium acetate was then determined by potentiometric titration with perchloric acid in an acetic acid medium.

The palladium electrode in aqueous and nonaqueous titrimetry
Analytica Chimica Acta, 1959Abstract Two modifications of the palladium-hydrogen electrode of Schwing and Rogers have been made and tested. A new form of “generation” electrode with a vertical palladium diaphragm and fast constant speed circulation has been devised. This form of electrode responds rapidly and has been used in a variety of acid-base titrations in aqueous and ...

End-point sharpness in thermometric titrimetry
Talanta, 1967It is shown that the sharpness of an end-point in a thermometric titration where the simple reaction A + B right harpoon over left harpoon AB takes place, depends on Kc(A') where K is the equilibrium constant for the reaction, and c(A') is the total concentration of the titrand (A) in the reaction mixture.

Titrimetry as a method of assessment of rumen contents
Veterinary Research Communications, 1986Titration of rumen fluid reveals the prevailing buffer system: VFA salts and sometimes bicarbonates in the normal state, ammonium salts or lactate in pathological conditions. Titrimetry appears to be a convenient method to study digestion in the rumen.
