CHEAQS Next is the next generation of the speciation program
CHEAQS Pro. The current version of CHEAQS Next is 2017.3, dated
7 July 2017.
Not known yet.
A fourth model for organic complexation was added, the one
developed by Cabaniss & Shuman (1988). Furthermore,
equilibrium definitions for gas-solution-equilibria can be
displayed. Also, a utility was added to delete user files in
case the program is uninstalled.
Two more titration types were added, including a real chemical
titration with volume change. Also, titration graphs can be
shown in log-mode.
A third titration type is added.
Pie graphs added as output option, log-values show during
output and some bug fixes.
Main new feature is the option to add items to the database
You can manipulate the database by removing or changing cations, ligands and species in an entirely new, easy-to-use interface (adding items to the database is foreseen for the near future).
In addition, CHEAQS Next remembers recent input and output files (if you like).
Convergence for high ionic strength samples was improved.
A bug causing a fresh installed program to hang was corrected.
Sorry for inconvenience.
Some features that are included in CHEAQS Pro are not yet implemented in CHEAQS Next, such as calibrations.
