Chemical Analytical labs


Inorganic analysis with Sample Preparations

We have broad experience in bulk and trace element analysis in both, solid and liquid samples (Cation and Anion analysis by Ion chromatography, ICP, XRD, (WD)XRF and micro-XRF, aqueous and non-aqueous titrations) in combination with sample preparation techniques for various applications.

Organic Separation Techniques and Sample Preparations

Our chromatographic and other separation techniques (TLC, LC, GC [DHS], GPC [SEC], SPE, SPME, …) apply to gaseous, solid or liquid samples, dispersions, emulsions, polymers and other materials. Depending on the material we can choose from a broad range of appropriate detectors (MS, DAD, RI, ELSD, CAD, Fluorescence, electrochemical, triple-SEC, FTIR, NMR). Preparative chromatography can also be applied for product and material analysis (reversed engineering). Our decade-long experience in sample preparation covers a wide range of materials, especially papers, polymer films, multilayered coatings or chemical coating or processing solutions.

Organic Spectroscopy and Structure Elucidation

Spectroscopy (MS, NMR, UV/VIS/NIR) and micro-spectroscopy (UV/VIS, FTIR, Raman, XRF, SEM-EDX) methods are applied as such or coupled with chromatographic techniques (GC, LC, TLC) that elucidate molecular structures of low and high molecular weight compounds (polymers) and formulations or materials, eventually at micron scale. Many special techniques, measurement cells and sampling accessories are available for dedicated experiments (mapping, imaging [FTIR-FPA], micro-ATR, DOSY-NMR etc.). The services range from rapid acquisition of chromatograms and/or spectra for interpretation by the customer (open access) to full problem solving with full interpretation and completed reports. The analytical expertise covers virtually all areas of chemical research and chemical production and we are countinuously involved in projects aiming at improvement of synthesis, process and production steps. Investigation of functional coatings in close cooperation with our other analytical labs (PHYS, OMT and HTT departments) is a core competence.
