We have the right analytical method for every measuring task
Gas chromatography (gc-ms & gc-fid)
Using gas chromatography (GC) coupled with a mass spectrometer (MS) or a flame ionisation detector (FID), we separate complex organic mixtures into the individual components and can then identify these materials and assess them quantitatively.
Gas chromatography (headspace gc)
Using headspace analysis, we identify and quantify highly volatile organic compounds. For this purpose only the headspace over a sample is analysed, not the sample as a whole. The substances in the vapour are analysed using GC-MS/GC-FID.
Ion chromatography (ic)
Ion chromatography is a sensitive method for the verification of ions in liquids. The individual ions are detected in a conductivity measuring cell after separation. Combination with other detector systems such as a UV/VIS detector and postcolumn derivatisation makes possible additional analysis options (HPLC).
Theromogravimetry (TGA)
Using thermogravimetric analysis, we quantify the composition of a material, e.g. the polymer and plasticiser content as well as the filler material content and the residual mass. For the exact identification and quantification of decomposition products released and volatile components, we couple TGA with FTIR spectroscopy and GC-MS.
Differential scanning calorimetry (dsc)
Based on differential scanning calorimetry (DSC), we determine parameters for the characterisation of the thermal properties of your material, e.g. glass transition temperature and melting point, enthalpies, degree of crystallinity, as well as the specific heat capacity.
Karl fischer titration (kft)
Using Karl Fischer titration (KFT), we determine the exact water content in analysis samples. The results of this method are independent of the type of sample as well as the presence of other volatile components and are available in a very short time.
RAMAN-Spektroskopie
By means of RAMAN spectroscopy, we identify inorganic and organic substances, liquids, fibres and very small particles. The spectrum acquired is compared to our comprehensive material databases.
Ftir spectroscopy
Using FTIR spectroscopy we identify, among others, plastics, fibres and very small particles straightforwardly and quickly. Both methods provide a spectrum that characterises the specific vibration of a molecule, a "molecular fingerprint" so to speak.
Scanning electron microscopy (sem-edx)
For the characterisation of the chemical element composition of materials and residues, we use energy-dispersive X-ray spectroscopy (EDX).

Frequently asked questions about chemical analytics (faq)
What is chemical analytics?
Chemical analytics or analytical chemistry addresses the identification (qualitative analysis) and quantification (quantitative analysis) of chemical substances. For this purpose there is an enormous variety of different methods, ranging from GC-MS to Karl Fischer titration, using which samples are analysed. In general the analytical methods can be differentiated into wet-chemical and instrumental methods.
What are wet-chemical analytical methods?
All methods during which the analysis of the analyte is only undertaken using wet-chemical methods are termed wet-chemical analytical methods, or in other words: no instruments are used for these methods. However, the term "wet-chemical" can be confusing because liquid chemicals are not used for every method. For example, the analysis of analytes using test papers (e.g. pH value) is a wet-chemical analytical method, even though only the analyte is a liquid. During the detection of metal ions using flame colouration, liquids play no role whatsoever, nevertheless this is a wet-chemical method.
What are instrumental analytics?
The term instrumental analytics refers to all methods in analytical chemistry during which instruments are used to analyse the analyte. The number of methods used in a modern chemical laboratory is enormous. Spectroscopic methods are often used, here the absorption of electromagnetic waves permits conclusions to be drawn about the composition of the analyte, or chromatography where a compound is separated into its different components and the composition of the sample determined based on the migration velocity of these components through a medium.
Where is chemical analytics used?
The applications are as varied as the methods used for the analytics. A very well-known field is the analysis of drinking water or the analysis of sewage as part of environmental analytics. Foodstuffs, cosmetics and other consumer products, which can be harmful for the health if contaminated with harmful substances or if the concentration of a specific substance is too high, must be regularly tested during quality control. As a rule, manufacturers task independent test laboratories with appropriate certification to undertake these tests.
