Relative retention in supercritical fluid chromatography as a source of partial molar properties
Article Abstract:
Supercritical fluid chromatography may also be used for measuring thermodynamic characteristics. The use of the relative retention of a pair of solutes to determine the solute partial molar characteristics in supercritical solvents has some advantages. The specific benefits of applying the relative retention are evident at the general thermodynamic level of the problem. Also, when the Flory-Huggins equation of state is used in combination with the regular solution theory, the corrections need pure-component parameters only. Lastly, the additional simplifications in the correction terms of isomeric solutes are explicitly included.

Cluster ion thermodynamic properties: the liquid drop model revisited
Article Abstract:
The reliability of liquid drop model in terms of predicting the thermodynamic properties of cluster ions and examining the rate convergence of thermodynamic properties to their bulk counterparts was investigated. Results show that the model predictions agree well with experimental data for a wide range of cluster sizes, including relatively small cluster sizes. However, the stepwise cluster thermodynamic properties converge slowly to their bulk counterparts for all cluster sizes.
