Expanded/renewed testing capabilities

In order to expand the testing spectrum of our laboratories, additional testing equipment has been purchased in the past and old equipment has been replaced:

XRF – X-ray fluorescence spectrometer (XRF)

XRF analysis allows the chemical elemental composition of a sample to be analyzed. This is done with the aid of primary X-rays. The sample is excited to emit fluorescence X-rays. Conclusions about the composition can be drawn from the spectrum of the radiation. Concentrations are expressed in parts per million (ppm). XRF analysis is used to determine whether a product is REACH/ROHS compliant.

XRF analysis is used to determine whether a product is REACH/ROHS compliant. Elements that are not desired can be excluded.

DSC – Differential Scanning Calorimetry

DSC is a thermal analysis technique used to measure the thermal energy released or absorbed by a sample during heating, cooling or an isothermal process.

DSC is used at the Krefeld and Doberlug-Kirchhain plants to analyze raw materials for foreign substances.

IR – Infrared Spectroscopy

Most molecules convert their absorbed energy, in the infrared range, into molecular vibrations. These absorptions are characteristic for chemical bonding ratios of a certain material.

At both sites, IR is used to analyze precursors. Here certain foreign substances can be detected.

Vicat – softening temperature

By determining the softening temperature, a plastic is quantitatively characterized.

A new Vicat instrument will be put into operation in the Krefeld laboratory in the near future.
