DataExpert is a comprehensive package for the production of user pure component databanks for subsequent use with the PPDS Thermodynamic Properties Suite. It uses proven techniques for data optimisation and fitting methodology, to provide a fully quality-assured route to the stored properties and fitted parameters in the user databanks. It provides a quality assurance trail for all the parameters produced and ensures that Thermodynamic consistency is maintained between properties when used to blend experimental data with validated estimated methods to create a complete quality-assured data record.

The optional NIST TRC data collection is quickly searched by DataExpert and evaluated constant and variable property data are extracted for subsequentanalysis for the chemical under review. Experimental data sets are screened to provide a thermodynamically-consistent input for fitting to established functional equations for each temperature dependent property. The user has complete control over the methods used and can see the results on-screen in a user-friendly graphical display.
