IsoFit  a tool for fitting isotherms to data 
IsoFit is a program that estimates
isotherm parameters by minimizing the weighted sum of squared
error between laboratory measured data and corresponding isotherm
computed values. IsoFit version 1.2 supports the following isotherms:
 BET (BrunauerEmmettTeller)
 Freundlich
 Freundlich with Linear Partitioning
 Generalized LangmuirFreundlich
 Langmuir
 Langmuir with Linear Partioning
 Linear
 Polanyi
 Polanyi with Linear Partitioning
Supported data weighting schemes include:
 Uniform (all data assigned equal weight)
 Individual (unique weights for each data point)
 SorbedRelative (proportional to inverse sorbed conc.)
 AqueousRelative (proportional to inverse aqueous conc.)
IsoFit executables for Linux and Windows, and an example input file
are provided in the zip file below, along with the manual.
