The department’s analytics group specializes in the characterization of natural and biomaterials (NREL analysis, fat analysis), polymer products and mineral components in recyclable materials (bitumens, railway sleepers, luminous coatings). In this context, comprehensive know-how has been built up in the detection of lignins, sugars, fats, and platform chemicals for polymer synthesis, using GC-MS, LC-MS, GPC, elemental analysis and ICP-OES.

HPLC analysis

Four devices with a variety of detectors (DAD, RID, MS ion trap, ELSD) are available. Beside carbohydrates, alcohols, amines and aldehydes, ditetrameric lignin breakdown products can be detected. MS-MS experiments can be carried out, and acid amides can be analyzed using light scattering methods.

GC analysis

In order to solve complex tasks in the area of fats and oils, product purity, monitoring of reaction processes and the characterization of monomeric lignin breakdown products, GCs are equipped with multifunctional sampling devices for HS and SPME, and with MS, FID detectors and TDS ovens.

GPC/SEC analysis

GPC combined with light scattering, viscosity and RI detectors is used to determine molar mass distribution in polyamides, polyesters and lignins. THF and HFIP are used as solvents.


Elemental analysis

The laboratory offers the possibility of comprehensive elemental analysis of inorganic and organic samples using MW breakdown and subsequent ICP-OES, or using CHNOS- and TOC analyzers. The sulfur content of organic matrices can be measured to an accuracy of 0.2%.


Titration methods

We can establish and validate automated titration methods for a wide variety of application fields. At present our repertoire includes KF titration, measurement of fat values in oils, OH values in polyols, amine values in PU and various other bulk parameters.


Emission analysis – test chamber methods and their applications

The analytics group currently operates a 1m3 climate chamber with online FID and online MS. For development tests or very small sample sizes, VOC emissions can also be measured directly at the GC/MS. We are accredited in the use of these methods, and are currently broadening our competences to include odor analysis methods.


Material characterization

In order to characterize plastics, identify material compositions and additives and measure changes in the material properties under increasing temperature, we offer comprehensive sample analysis using thermogravimetric mass spectrometry.
