Spectra library, additive quantification, early detection of abrasion and wear, analysis of impurities

By using state-of-the-art analytical methods such as infrared spectroscopy, wavelength-dispersive X-ray fluorescence analysis and gas chromatography, we can determine the basic chemical components of lubricating greases, oils and fuels such as additive concentrations, abrasion and wear elements as well as impurities. We have direct access to a spectra library that references a large number of lubricants as "fingerprints" for quality assurance purposes.

Accredited test procedures

  • The proficiency of our test laboratories in Munich for testing in the following areas was accredited by Deutsche Akkreditierungsstelle GmbH (DAkkS): physical, physical-chemical and chemical analyses of lubricants; element quantification in lubricants via wavelength-dispersive X-ray fluorescence analysis; sampling of lubricants.
  • The entire list of our accredited test procedures can be found in our ​accreditation certificate.
  • DB Systemtechnik is QMS certified to the ISO 9001 standard.

Spectra library

Every lubricant approved for DB AG is characterised by an infrared spectrum and can be uniquely identified by this "fingerprint". This, in turn, allows the lubricant used to be identified accordingly, which in most cases is also possible when unknown samples are encountered. Our spectra library now references over 450 spectra of lubricants in active use.

Additive quantification

Qualitative and quantitative determination of additive elements via X-ray fluorescence and infrared analysis makes it possible to identify whether the lubricant used still has a sufficient quantity of additives or must be replaced.

Early detection of abraison and wear, analysis of impurities 

By continually monitoring lubrication systems and conducting trend analyses, it is possible to ascertain when a lubricant must be replaced or a component has or is soon to become damaged. This, in turn, allows lubrication replacement intervals to be optimised and extensive damage avoided.
