Competence for your analytic enquiries

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 examine your specimens and resolve your problems.
We cover the following main fields for you. The performance portfolio varies depending on the CHT site. Our technicians will be pleased to provide you with more detailed information. 

The following analytical techniques are at our disposal:

• Gas chromatography (among others GC-MS, Head-Space-GC)
• HPLC (with RI and UV detector)
• GPC (in organic solvents)
• Thin layer chromatography
• UV / VIS spectroscopy
• FT-IR spectroscopy
• Thermal analysis (TG, DSC)
• Titration processes (among others water content according to Karl-Fischer)

Water analysis

• Determination of the quality criteria and components of industrial water such as appearance, pH value, conductivity, salt content, hardness, TOC, cations and anions.
• Measure of the waste water load with the most important waste water characteristics COD, TOC, BOD5, AOX, hydrocarbons, lipophilic substances, heavy metals, nitrogen, phosphorus, daphnia toxicity (L 30) and other parameters depending on the enquiry

Product analysis

• Biodegradability according to the international stipulations 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)
• Flame point determination

Metal analysis

In the chemical analysis the ICP-OES is a common process for determining metals; we can among others quantitatively determine Ag, Al, Ba, B, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Sb, Si, Sn, Ti, Zn and Zr, as well as P and S according to DIN EN ISO 11885 (E 22).
