A practical two-state thermodynamic analysis tool for calorimetric and spectroscopic data
This program helps scientists interpret differential scanning calorimetry and spectroscopy data using a two-state model. It fits X,Y data to two-state equations with an iterative least-squares approach and shows how parameters like enthalpy, heat capacity, and Gibbs energy vary with temperature. The tool also functions as a general data-analysis program with plotting, data transformations, and baseline handling.
The software is designed to be menu-driven and graphically oriented, making it possible to enter data, view fits, and compare results from different data files. It includes detailed options for initializing estimates, testing convergence, and constraining parameters to explore different modeling scenarios. Examples and a thorough reference guide accompany the program.
- Fit calorimetric and spectroscopic data to a two-state equilibrium model
- Perform baseline construction, initial estimate selection, and parameter constraints
- Apply data transformations, scaling, and various display options to diagnose fits
- Save fits and residuals, compare multiple analyses, and view graphical outputs
Ideal for researchers analyzing transition profiles in proteins, nucleic acids, lipids, and other macromolecules. This edition presents clear workflows for two-state fitting and practical guidance on producing reliable parameter estimates.
