Kinetics Lite
Software for basic kinetic analysis of TGA/DSC measurements for chemical processes using both model-free and single-step model-based kinetic methods. Prediction of process behavior for isothermal or constant heating conditions.
What Is Kinetics Lite
Kinetics Lite is the basic version of software for analysis of rate of chemical reaction depending on the temperature. Simple examples of such reactions are decomposition, storage of thermally instable materials, chemical aging, curing above glass transition temperature.
Data for analysis are measurements carried out on NETZSCH thermal analysis instruments. The software can analyze experimental data of Differential Scanning Calorimetry (DSC) or Thermogravimetry (TG) which are transferred from Proteus Analysis to Kinetics Lite by one click. For each analysis method Kinetics Lite provides simulated fit and R² for its quality. Results of kinetic analysis can be used for isothermal predictions at user-defined temperatures or for user-defined heating rates.
Curing of epoxy resin: experimental DSC points and simulated curves according to model-free (isoconversional) Friedman analysis with fit quality R²=0.999
Kinetics Lite contains well-known model-free analysis methods such as single-point isoconversional methods (ASTM E698, ASTM E2890, ASTM E1641) and multi-points isoconversional methods (Friedman, Ozawa-Flynn-Wall and Vyazovkin).
Curing of epoxy resin: Model-free Friedman plot with experimental DSC points and isoconversional lines for selected conversion levels
Curing of epoxy resin: Activation energy with error bars as the function of conversion for model-free Friedman method.
Kinetics Lite contains model-based methods for single-step reactions of mostly used reaction types based on Arrhenius law, such as reactions of n-th order, autocatalytical and nucleation reactions.
Decomposition of Ca(OH)2: experimental TGA points and simulated curves according to n-th order kinetic model with fit quality R²=0.999
Both model-free and single-step model-based results of kinetic analysis can be used for predictions at isothermal or constant heating conditions.
Isothermal predictions of crystallization for LDPE based on single-step kinetic model according to Avrami. Final conversion corresponds to experimental peak area.
Integration with Proteus Software
Kinetics Lite is deeply integrated into NETZSCH Proteus software. Data can be loaded into Kinetics Lite directly from Proteus® Analysis software. Customer should purchase Proteus option Kinetics Lite.
This option inside Proteus package can be purchased together with NETZSCH instrument DSC, TGA or STA.
System Requirements
System Requirements for the NETZSCH Kinetics Lite software are similar to requirements for NETZSCH Proteus software.
