The analysis of raw materials, products, functionalized materials as well as plant and waste water is an important part of our daily work and a core competence of the CHT Group.
High performance analytic laboratories with top modern analysis devices and a highly specialized staff are worldwide at our disposal. The high competence and quality of our analytic laboratories, particularly for the instrumental analytics and environmental analytics at our site in Tübingen, are confirmed by accreditation through DAkkS (The German national accreditation body) according to DIN EN ISO / IEC 17025.
Benefit from this service and let us analyze your specimens and resolve your problems. The performance portfolio varies depending on the CHT site. Our technicians will be pleased to provide you with more detailed information. We cover the following core areas for you in total.
Instrumental analytics deals with versatile tasks. We examine formulations, raw materials, polymers, coatings, residues and many more.
The following analytical techniques are at our disposal:
- Gas chromatograpy (i.a. GC-MS, Head-Space-GC, Pyrolysis GC-MS, TDS)
- HPLC (with DAD and MS detection)
- GPC (in organic solvents)
- Thin layer chromatography
- UV / VIS spectroscopy
- FT-IR spectroscopy
- Thermal analytics (TGA, DSC)
- Titration processes (i.a. water content according to Karl Fischer)
- Laser diffraction - particle size analysis
The behavior of chemicals in the environment and their ecological evaluation are of great importance. Therefore, we carry out the necessary tests in our own laboratory and state the corresponding information in our safety data sheets (SDS).
These values are simultaneously the base for the ecological evaluation and classification in waste water relevance classes (ARS in Germany). Our experts of the plant water analysis examine the quality of the industrial water and our waste water analysis experts determine the type and degree of soiling.
- Determination of quality criteria and water components of process water, such as appearance, pH value, conductivity, salinity, hardness, TOC, cations and anions
- Measurement of the wastewater load with the important wastewater characteristics COD, TOC, BOD5, AOX, hydrocarbons, lipophilic substances, heavy metals, nitrogen, phosphorus, Daphnia toxicity (L 30) and other parameters, depending on the problem
- Biodegradability according to the international regulations OECD 301 A, OECD 301 B, OECD 301 F and OECD 302 B
- Activated sludge toxicity according to OECD 209
- Aquatic toxicity according to OECD 202 (Daphnia)
- Flash point determination
ICP-OES and ICP-MS for the determination of metals are widely used methods in chemical analytics and we can determine almost all elements quantitatively according to DIN EN ISO 11885 (E 22) or DIN EN ISO 17294-2 (E29). Different degradation methods are available
