ppmfit
7.0 | 1.3.2
This program can be used to fit pKa values to pH dependent data where the data titrates from one value to another e.g. ppm data, absorbance data, fluorescence data, Ki and Km data etc.
The program fits and plots data to the equations:-
If one pKa only
Sobs=S1(1+K1/H)+S2/(1+H/K1)
If two pKa values
Sobs=(S1*H^2+S2*KA*H+S3*KA*KB)/(H^2+KA*H+KA*KB)
