Get in touch with our experienced analytics team

Our customer-oriented analytics team has years of practical experience and is happy to provide you with advice and support. We boast comprehensive product know-how and recent project experience. We combine state-of-the-art analytical methods with analytical expertise to offer you an efficient solution. We test polymer materials and their raw materials, additives and fillers using cutting-edge methods. Depending on the type of polymer, we adapt the methods for the qualitative and quantitative determination of your samples to your specific requirements. We have many years of experience in this area – particularly when it comes to polyurethanes, coatings, rubbers and thermoplastics.

When it comes to identifying polymer matrices, we generally use IR and NMR spectroscopy, which we sometimes combine with mass spectrometry, if the situation calls for it, e.g. pyrolysis gas chromatography mass spectrometry (Py-GCMS) or matrix-assisted laser desorption/ionization (MALDI). These techniques are often used in tandem with one another as part of special sample preparation procedures. By combining the various testing methods, we will ideally be able to completely characterize the polymer matrix. The process of characterizing polymers is completed by determining the molecular weight distribution, which we can do using gel permeation chromatography (GPC) with a variety of eluents, for example.

In addition to determining the polymer matrix, we also identify and quantify the additives in your samples. In doing so, we use our wide-ranging portfolio of analytical methods and optimize them according to your specific requirements. We often use spectroscopic/spectrometric and chromatographic methods or combinations of these techniques. The key identification methods are gas chromatography mass spectrometry (GCMS), IR and NMR spectroscopy and thin-layer chromatography. Additives are usually identified and, if requested, subsequently quantified after the first enrichment step in which they are initially separated from the polymer. This can be done through extraction with the appropriate solvents, for example. When it comes to additives, our core skills lie in analyzing antidegradants, thermal stabilizers, UV protection agents, lubricants, waxes, emulsifiers and plasticizers.

Besides identifying additives, our primary area of expertise when it comes to rubbers lies in analyzing elastomers, thermoplastic materials and vulcanizates. Analysis is conducted by determining particle sizes and molecular weight distributions, conducting structural analyses, and quantifying additives and thermoanalytical characteristics. In addition to determining the chemical composition, we also offer particle size and molecular weight distribution determinations, structural analyses and thermoanalytical characteristics.
