ReactLab™ KINSIM offers extensive modelling and simulation capabilities for complex chemical reaction systems. Based on the specified reaction mechanism, its rate constants and the initial concentrations for the reactants, complete concentration profiles for all reactants and products are computed and plotted. ReactLab™ KINSIM allows the modelling of very complex reaction mechanisms which may also include instantaneous or equilibrium processes, e.g. fast protonation equilibria. Model entry is user-friendly as ‘normal’ chemical reaction equations based on standard notation can be used.

The program, including all algorithms and the GUI frontend, have been developed in Matlab and compiled to produce the final deployable application.

Model entry and computational output are organised in Excel Workbooks, which are launched from, and dynamically linked to, the ReactLab™ application. Similarly, all numerical analysis options are organised in the Excel format. It is therefore necessary for Excel to be installed on the same computer as ReactLab™.

These results can be further analysed, graphed or reviewed, just using Excel.

A selection of example workbooks accompanies the program in an Excel template subfolder; they are described in detail in Part 2 of the provided user manual.

An example simulation of an enzyme reaction mechanism using ReactLab™ KINSIM is show below:

Reaction models and conditions are setup in specially formatted Excel workbooks. All numerical calculations are performed by the ReactLab KINSIM program and the results presented in its graphical user interface. The results are also exported to the Excel workbook which allows further analysis and charting of the modelling results without the need for ReactLab KINSIM and according to the particular requirements of the user.

Kinetic simulation is probably the most effective way of learning about the dynamics of chemical reaction processes. It provides insight into the behaviour of reactions and allows prediction of relative species and product concentrations under varying conditions. It is also an invaluable tool for planning experiments.
