ReactLab KINETICS & EQUILIBRIA – build09 now available

This new build fixes a compatibility problem arising with Excel 2016 in which an ‘incomplete worksheet entry’ was raised when trying to update or fit a model to data.


ReactLab KINSIM PLUS now FREE

We are pleased to announce that ReactLab KINSIM PLUS for the simulation and modelling of reaction kinetics is now to be made freely available and is renamed ReactLab KINSIM. This remains version 1, but Build 2, and replaces the former free version of the program, also called ReactLab KINSIM but offering fewer features. You can see more details here.


NEW ReactLab KINSIM

We are pleased to announce the launch of ReactLab KINSIM for the simulation and modelling of reaction kinetics. The standard version of the software is available FREE.

You can download the free version from the product page here.

ReactLab KINSIM PLUS is a licensed version of the program which offers additional features including dynamic parameter sliders allowing interactive adjustment of rates and equilibrium constants.

Like other ReactLab programs KINSIM has a compiled Matlab computation engine and uses Excel workbooks for defining the model and all the simulation output, allowing flexible presentation and sharing of the results.


New Jplus Website

We are pleased to announce the launch of our new website. We would like to thank Bevin Design for their efforts on the project.


ReactLab Version 1.1 Build 08 now available for download.

Key New Feature release:

  • Automatic export of Residual matrix to a separate worksheet in ReactLab workbooks.
  • Fit Plot worksheet added to templates for fit visualisation at selected wavelengths.
  • ReactLab™ EQUILIBRIA and ReactLab™ KINETICS now both support analysis of measurements made at a single wavelength.

ReactLab Version 1.1 Build 07 now available for download.

Recommended maintenance upgrade: details in installation readme file:

  • Fixes workbook load error when the data sheet contains more than 2700 wavelength columns.
  • Fixes error causing incorrect display of data and fit in Graph GUI when cell pathlength is not 1cm.
  • Fixes error when SVD dialog is opened with fewer than 10 data rows.

ReactLab Version 1.1 Build04 now available for download.

Maintenance upgrade:

Graphic GUI zoom/unzoom behavior corrected.

Workbook sheet protection revised to allow easier reformatting of cells and columns.

ReactLab Equilbria only; total component concentrations in data sheet left in place on model re-compilation and moved if component column changes.


Intech Open Access Publication: Chemometrics in Practical Applications

Jplus co-founders Marcel Maeder and Peter King have contributed the Chapter; “Analysis of Chemical Processes, Determination of the Reaction Mechanism and Fitting of Equilibrium and Rate Constants” to the Intech Open Access publication; “Chemometrics in Practical Applications”

www.intechopen.com/books/chemometrics-in-practical-applications

Chapter 3 describes some of the principles and theory underlying the application of global data fitting for the characterisation of chemical reaction mechanisms and is illustrated with ReactLab™ analysis examples.
