Material structure analytical tests
Material structure analytical tests represent one of the most important areas of the plastics and polymer industry, as these methods reveal the internal structure, composition, crystallization behavior and chemical bonds of samples. In modern manufacturing processes – especially in the automotive, electronics, packaging and construction industries – it is essential to know exactly what raw material a product is made of, how it reacts to heat, load or aging, and what modifying additives are found in it.
In this area of testing, MÜKI LABOR employs advanced analytical techniques that enable the rapid and precise determination of material structure, purity, degradation, or even the root cause of failure. The combination of thermoanalytical and infrared spectroscopic methods provides high-level support for research and development, quality assurance, and troubleshooting activities.
Differential Scanning Calorimetry (DSC)
Differential scanning calorimetry is one of the most important thermoanalytical methods for investigating the structure and thermal behavior of polymers. DSC measurements can determine the melting, crystallization and glass transition temperatures of amorphous and partially crystalline plastics, as well as their associated enthalpy values. The method is particularly suitable for material identification, comparing different production batches and investigating the causes of quality problems.
The test also allows the determination of oxidation induction time (OIT) and temperature, which are important information about the aging behavior and stability of polymers. DSC is an indispensable tool in development and quality control processes, helping to understand the internal structure and thermal properties of the material.

Infrared spectroscopy material analysis (IR, FT-IR)
Infrared spectroscopy is one of the most accurate methods for determining the chemical structure of plastics and polymers. During the test, the infrared spectrum of the sample is recorded, which shows the molecular structure as a specific, repeatable “fingerprint”. The method is suitable for identifying functional groups, chemical bonds, additives, aging processes, degradation or foreign contaminants
The test is performed using several techniques: transmission, ATR, total reflection and diffuse reflectance. It can be used for fault detection, comparison of two products, material identification and development purposes. The advantage of the method is that it is fast, accurate and requires minimal sample preparation.

Material structure analytical tests for detailed material identification of plastics and polymers
The role of structural analysis in industrial quality assurance
Examining the structure of materials is essential when:
– the composition of an unknown material must be determined,
– the difference or identity of two raw materials must be proven,
– the cause of manufacturing defects, cracks, tears or aging phenomena must be discovered,
– objective laboratory results are required for complaint management,
– the goal is to optimize a product under development.
Analytical methods can reveal crystal structures, melting points, bonding types, oxidation processes, or even chemical modifications of polymers. These data are essential for industrial quality assurance and compliance with standards.
Analytical methods on which our tests are based
We use several complementary modern technologies for material structure analyses:
Differential Scanning Calorimetry (DSC)
The method examines the response of polymers to heat, thus determining the melting point, glass transition and crystallization temperatures, as well as the associated enthalpy values. DSC is particularly suitable for material identification, identifying the causes of quality problems, and monitoring production parameters.
Infrared spectroscopy (IR, FT-IR)
The IR spectrum provides a kind of “fingerprint” of the polymer’s molecular structure. The method can be used to detect characteristic functional groups, bond types, additives or their changes. It is excellent for material identification, defect detection, analysis of aging processes or comparison of two products.
The test is performed using several techniques: transmission, ATR, total reflection and diffusion methods.
The analysis is performed using several techniques, including transmission, ATR (attenuated total reflectance), total internal reflection, and diffuse reflectance methods.
Combining the above methods provides a complete picture of the material structure, making it suitable for supporting more complex quality or problem-solving tasks.
Where can material structure analytical tests be applied?
These tests are indispensable for a wide range of industrial players:
– material identification and development of automotive components,
– inspection of food, pharmaceutical and cosmetic packaging materials,
– quality assurance of extruded and injection-molded products,
– testing of coatings and decorated surfaces,
– investigation of manufacturing defects and complaints.
