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.

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 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.

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%.

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.

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.

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.
