Welcome to Our Site

At Jplus we have developed the ReactLab™ suite of software tools that enable scientists to model chemical processes and analyse spectroscopic experimental data to quantitatively characterise the underlying reaction mechanism.

Based on proprietary multivariate algorithms ReactLab™ global analysis tools are able to provide greater insight than classical data fitting methods and allow the robust determination of parameters that are otherwise difficult to obtain.

Any scientist carrying out kinetic investigations or equilibrium titration experiments to characterise reaction mechanisms and determine the underlying rates and equilibrium constants will benefit from our programs.

We offer a range of applications and are constantly enhancing these products. We can provide a variety of flexible licensing options and have built an excellent reputation for providing prompt support and advice to our customers.

"...by the way, congratulations on the software, it works really nicely."...Prof. Pablo Ballester, ICIQ, Tarragona, Spain

Global Analysis and Reaction Modeling

Whilst data fitting of spectroscopic measurements is well established as a tool for determining the rates and equilibrium constants of chemical reactions classical approaches are often laborious and indirect.

ReactLab™ algorithms fit complete reaction models directly to multivariate data and delivers all the required parameters in one step. The analysis also yields the concentration distributions of all species and for multi-wavelength data, the individual spectra of all the participating species.

Compatible measurements include: Absorption, Fluorescence, NIR, IR, Raman, ESR and CD.
