Separating Overlapping Effects in Analytical Measurement Curves
One of the advanced features within the Proteus® software is the PeakSeparation function. It is used to separate super-imposed peaks in thermal analysis curves and accurately determine individual peak areas. Learn more watching our latest webinar.
Nowadays, software is one of the most important aids in the preparation, execution and evaluation of thermal analysis experiments. The NETZSCH Proteus® software is easy to operate and contains all of the instrument-specific settings, control operations, data storage options and evaluation routines in a single package. Today, we are going to present PeakSeparation, an advanced Proteus® software extension: If your experimental curve looks very complex with several maxima and seems to contain multiple overlapping peaks, then PeakSeparation can help separate these peaks and analyze each peak individually.
PeakSeparation for Accurately Determining Individual Peak Areas
Peak separation can be applied to thermoanalytical measurements such as DSC/DTA curves, TGA and DIL curves, IR traces and MS curves. With PeakSeparation, each peak is analyzed individually and peak parameters such as shape type (Frazer-Suzuki, Gauss, Cauchy, Laplace etc.), position of peak (temperature), height, width and area (e. g., enthalpy of the DSC peak) are reported.
In our latest webinar, presented by Dr. Stefan Schmölzer, our applications laboratory expert, you will learn about:
- What PeakSeparation is and why we need it
- Application examples for PeakSeparation:
- Melting Temperatures and EnthalpiesThe enthalpy of fusion of a substance, also known as latent heat, is a measure of the energy input, typically heat, which is necessary to convert a substance from solid to liquid state. The melting point of a substance is the temperature at which it changes state from solid (crystalline) to liquid (isotropic melt).Melting of polybutylene terephthalate (PBT) using Differential Scanning Calorimetry (DSC)
- Polyamide with carbon fibers using Thermogravimetric Analysis (TGA)
- Loam using simultaneous application of Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC)
PeakSeparation is a useful tool for interpreting thermal analysis curves, such as those obtained from thermoanalytical measurements, to gain additional information. It is optionally available in Proteus®® 8.0.3.
The new Proteus® 8.0.3 version is available as a free download for all existing Proteus® 8.0/8.0.1/8.0.2 customers. Proteus® 8.0.3 includes many improvements and functional extensions. Ask your representative about the possibility to update your instrument with the latest software and keep your instrument up-to-date.
