Identification and quantification of ceramic degradation products
ISO 10993-14:2001 describes several analytical tests to identify and quantify degradation products from ceramic implants. In our laboratories we are able to perform the dissolution test and the quantification of degradation products. Further tests for a complete characterization according to ISO 10993-14:2001 can be performed in-house or in collaboration with partner laboratories.

Identification and quantification of inorganic crystalline phases in powder samples
Identification and quantification of inorganic crystalline phases in powder samples by X-ray diffraction (XRD) is done in collaboration with the Institute of Geology at the University of Bern. Data processing using state-of-the-art Rietveld refinement methods provides quantitative phase compositions and crystallographic parameters of main phases. In addition to conventional dry powder samples, the setup allows to analyze high-temperature samples in-situ at temperatures up 1200 °C, as well as curing cement samples in wet condition.
