Hyperquad2013

Equilibrium Constants from Potentiometric Data

© 2013 Protonic Software

Hyperquad2013 is a Windows™ application that can that can be used to derive equilibrium constants from experimental data. The data are usually obtained by means of potentiometric titration. Hyperquad2013 is the latest in a long series of developments. The original basis for the stability constant refinement of an earlier version has been published: P. Gans, A. Sabatini and A. Vacca, Talanta, (1996), 43, 1739-1753. view paper (requires Acrobat reader). The 2013 version has many improvements and uses a revised algorithm, making it more powerful and reliable than ever before. For references to published papers see applications.
