Thermokinetics

 

see also: Algorithm of Kinetic Analysis, Applications

The basis of analysis are measurements, executed with the methods:

thermogravimetry (TGA),
differential scanning calorimetry (DSC, DTA),
mass spectrometry (MS),
dilatometry (DIL),
rheometry and its special variant vulcametry (RHEO, VULC).

The general interface to measurement data are ASCII files

In the program Thermokinetics are integrated various methods of kinetic analysis and of predictions as well as

 

Model-free Kinetic Analysis 

   Friedman analysis of dynamic and/or isothermal measurements

   Ozawa-Flynn-Wall analysis of dynamic measurements

   Analysis according ASTM E698

 

Model-fit using Multivariate Nonlinear Regression

Model definition, including multiple step reactions and 18 different reaction types
Conditions for parameters

Visual optimization in order to achieve a good start position for the nonlinear regression 

Nonlinear regression. Conditions of iteration. Results are:
- optimized parameters including standard errors
- F-test regarding the fit quality
- F-test regarding significance of an additional step
- Graphic presentation

NETZSCH offers instruments for thermal analysis, thermal properties measurement, thermal hazard screening, and contract testing services. Our portfolio is the world's broadest, including a full range of dilatometers to measure high accuracy thermal expansion, classical DSC & TGA, high temperature DSC to 1650°C for specific heat, very high temperature STA (TGA-DSC/DTA) from sub-ambient to 2400°, thermal / evolved gas analysis with fully-integrated FTIR & MS, high resolution TMA and DMA, plus DEA - dielectric analysis for thermoset cure monitoring. We also feature leading-edge technology for thermal conductivity by guarded hot plate and heat flow meters, laser flash thermal diffusivity measurement, thermal hazard screening via adiabatic reaction calorimetry, as well as refractories testing including HMOR, CIC, and RUL. Finally, we offer advanced software packages including thermokinetics for process modeling and development.
