PTG/e can be an extension of your in-house R&D. Whether it is contract research or simply the analysis of a material, you can count on us for professional support. We take a pragmatic approach, which translates into short communication lines internally and regular contact between our researchers and the customer. In this way we can monitor project progress and steer the process as needed.

Our services include organising postdoc-level open courses. And thanks to our large network of lecturers, we are also able to offer (in-house) courses tailored to your specific needs.

PTG Eindhoven is your research partner in material innovation and material research.

Research & innovation

Need an experienced partner to complement your in-house R&D from time to time? For example when you are short of capacity or do not have the necessary material expertise in house?
PTG/e is fully equipped to take on a variety of tasks.

Also for shorter term projects, PTG/e is your partner. Comparison of raw materials, material identification or a quick literature scan – these are just a few of the services that PTG/e can perform for you.


With access to a wide network of (own) experts in many areas of chemistry, PTG/e is excellently placed to help you expand your knowledge of polymers. We are organizing customized company specific courses, as well as open PTN courses.


TGA-IR-GC-MS: A powerful evolved gas analysis technique

The TGA-IR-GC-MS analysis is an analytical method that integrates three powerful techniques: thermogravimetric analysis (TGA), infrared spectroscopy (IR), and gas chromatography-mass spectrometry (GC-MS). When combined, they form an analytical synergy that provides comprehensive information on a material’s chemical properties. TGA-IR-GC-MS analysis is a powerful evolved gas analysis technique which we are using at PTG/e for many different applications.

Some examples of projects we have carried out for our customers are:

  • Polyurethane characterization: Identifying the building blocks of polyurethanes, which can be valuable for material development.
  • Ink formulation analysis: Determining the composition of unknown cured ink formulations.
  • Polymer analysis: Identifying plasticizers and additives in polymers, which is essential for understanding polymer properties.
  • Thermal degradation studies: Investigating the thermal degradation of various polymers, which gives information about their use in various applications.


How does it work?

The TGA-IR-GC-MS analysis is an analytical method that integrates three powerful techniques: thermogravimetric analysis (TGA), infrared spectroscopy (IR), and gas chromatography-mass spectrometry (GC-MS). Each of these techniques offer unique insights into a material’s composition, molecular structure, and thermal behavior. However, when combined, they form an analytical synergy that provides comprehensive information on a material’s chemical properties.

At this photo you see the TGA-IR-GC-MS setup at PTG Eindhoven. A powerful gas analysis technique for many different applications.

Within PTG/e’s infrastructure, TGA, IR, and GC-MS equipment can be combined with a heated transfer line. The TGA technique quantifies a sample’s weight change as a function of temperature or time. It subjects the sample to a precisely controlled temperature program while continuously monitoring its weight. This enables the determination of critical information related to a material’s thermal stability and decomposition behavior.

In this graph you see the thermogram of a polymer material, showing the weight percentage as a function of temperature. TGA-IR-GC-MS is a great analysis to combain 3 powerfull techniques. We, at PTG Eindhoven, are very experienced in TGA-IR-GC-MS.

The gas that evolves from the sample by evaporation or thermal decomposition during the TGA measurement, is transferred via the heated transfer line through the IR gas-cell to be measured with IR spectroscopy. IR spectroscopy uses the interaction between infrared light with the molecular bonds within the evolved gas, which is unique for each type of material. The spectrum that results from this technique reveals valuable details about the functional groups within the evolving gases, aiding in the identification of chemical bonds, molecular structure, and functional groups of the original sample.

The gases that evolve from the sample at a specific temperature during the TGA measurement, can be collected to inject into the GC-MS. In GC the gasses (which are likely to be mixtures of various components) pass through a separation column, separating the individual components based on their volatility and column affinity. Then, MS analyzes these separated components, providing information regarding their molecular mass and fragmentation patterns. This helps identify the components released during thermal degradation of the material, providing further insight into the original composition of the material.

The flexibility of the whole evolved gas system offers several combinations of techniques including: TGA-IR, TGA-MS, TGA-GC-MS and TGA-IR-GC-MS analyses. This makes it possible to select the best combination of techniques to answer the material questions.

In conclusion, the combination of the TGA, IR, and GC-MS techniques presents a potent analytical tool capable of resolving complex and unknown material challenges.

NEW UV-vis Spectroscopy

We are excited to announce a new addition to our infrastructure, UV-vis spectroscopy. UV-vis spectroscopy is a powerful tool for determining how molecules and materials interact with light. For a range of wavelengths, a beam of monochrome light is passed through the sample.

Suitable samples absorb part of the light within a specific wavelength range, which provides information on the concentration of certain molecules in a sample when compared to a reference of known concentration. Additionally, UV-vis spectroscopy can be used to follow the kinetics of (chemical) reactions occurring in a sample over time.

Curious about what UV-vis can do for you? Feel free to reach out and discover the possibilities
