Dear Ivano,

I have used your CurTiPot program, and find it very useful and powerful.

Curtipot - A spectacular acid-base titration spreadsheet

CHE 133 Syllabus and Shedule
Stony Brook University

...CurTiPot, a Microsoft Excel (Redmond, WA, USA) spreadsheet, presents particularly detailed information on ionization states and activity coefficients. It also simulates virtual acid–base titrations, and performs multiparametric nonlinear regression to recover concentrations and/or pKa's of multiple species from experimental titration data. ... Of these packages, we recommend CurTiPot for most acid–base problems, PeakMaster for simple electrophoresis problems where ion mobility and buffer conductivity are relevant; and Simul or Spresso for acid–base equilibria in full-scale electrophoresis simulations.

Dear Dr. Gutz,

I found your Curtipot program from the Buffer solution page on Wikipedia. I very much like it. I plan to use it in classroom demonstrations here at Rice University.
Great job on the program!

Thanks,
