Accredited testing

For many years, standardized and internally as well as externally validated processes and procedures at Fraunhofer IGB have been safeguarding a reliable and consistent quality of our services and products. An efficient quality management system ensures that selected test procedures are accredited according to the international DIN EN ISO/IEC 17025 standard.


The accreditation of reference laboratories and test procedures of our analytics according to DIN EN ISO/IEC 17025 guarantees that our proprietary, in-house test methods and procedures are validated and that the quality of our tests is assured even where no standardized methods are available.

Accredited analytical methods and test procedures:

  • High-performance liquid chromatography (HPLC)
  • Ion chromatography (IC)
  • Gas chromatography (GC, GC/MS)
  • Atomic emission spectrometry (ICP-OES)
  • Electron spectroscopy for chemical analysis (ESCA/XPS)
  • In vitro cytotoxicity testing (DIN EN ISO 10993-5)
  • In vitro phototoxicity testing

Accredited biocompatibility and phototoxicity testing

With our in-house method for in vitro testing of phototoxicity, we can investigate solutions and substances with respect to their phototoxic potential on our in-house designed three-dimensional skin model. The test method is in accordance with the OECD Guideline 432 and the INVITTOX Protocol no. 121.

Certificates and QM manual

The accredited testings are certified on the certificate and in the appendix to the certificate. With our QM manual, we document our QM system in the reference laboratories and describe quality assurance measures and responsibilities.
