Chemical Analytics and Cleanliness Analysis

• Density, viscosity, water content
• Neutralization number
• Determination of purity classes
• Determination of flash points
• Corrosion effect of oils on copper
• NMR spectroscopy (e.g. analysis for misfueling or similar)

and much more

Testing of cooling lubricants, corrosion protection agents, cleaners
testing of industrial waters and waste waters
complex determination of characteristic data for production aids
Testing for fine dirt.

The wide range of competences, including organic and inorganic chemistry, material and coating technology, as well as component cleanliness, is just as characteristic for our employees as the ability and willingness to flexibly familiarize themselves with new problems.

For this purpose, state-of-the-art testing technology is available in our laboratories, with which the relevant analyses are carried out and evaluated in a timely manner.

The purpose of cleanliness testing is to measure the particle contamination present on relevant surfaces of the test object, as they result from manufacturing processes and the environment, as completely and accurately as possible.

For manufacturers, suppliers or cleaning service providers, precise investigations into the type, nature and origin of the contamination are therefore of ever-increasing importance.

Cleanliness analysis according to VDA 19 / ISO 16232 as well as other customer-specific test standards (BMW, Daimler, VW, etc.)

Particle extraction by means of spraying, rinsing, ultrasound, dipping, etc…

• gravimetric residual dirt determination
• light microscopic particle evaluation
• particle counting (manual and automated)
• particle analysis IR, EDX

Accredited Standards Stands for Cleaning Analysis

ln the practice of damage analysis, we assess changes to components that impair or make impossible their intended function or that are expected to impair it. Deviations between the intended and actual condition of the component are documented, and a wide variety of influences to which the component has been exposed are simulated and predicted.

For this analysis, we have a wide range of macroscopic and microscopic methods of plastics testing and diagnostics at our disposal.

Since the mechanical properties of plastics in particular are much more affected by temperature and time than those of metallic materials, special attention is paid to these influencing factors in conjunction with the manufacturing condition.

For damage prevention, we advise you in accordance with the selection and application areas of the materials, from chemical resistance to mechanical wear resistance and corrosion resistance.

Another major subject area of the division comprises the testing of initial samples with regard to their conformity with OEM specifications.

In cooperation with the client, our engineers draw up specific test programs and evaluate the results.

If deviations occur, we can make recommendations for optimization.
