  Physico-chemical analyses: Thermal, chemical, spectroscopic analysis, etc.
  Physicochemical analyses enable the analysis of materials and their characteristicsin order to confirm their compositions or identify defects. Depending on the problems encountered, various analytical techniques can be implemented:
  • Metallic materials : SEM-EDX, ICP or SEO chemical analysis, GDMS, etc.
  • Organic materials : FTIR spectroscopy, Raman spectroscopy, DSC, GC / MC, etc.
  • Mineral materials : SEM-EDX, XRD, (...)

  FORENSIC EXAMINATION : ACCOMPANYING EXPERTS IN DISPUTE RESOLUTION
  A part of forensic examinations and/or dispute resolution, an expert must call upon a service provider or specialist advisor laboratory to conductimpartial and technical investigations. In the ANALYSES & SURFACE laboratory, the expert finds the skills and the means with which to analyze all types of materials (metallic, mineral, organic), particularly in the fields of civil engineering, building/housing or industry. (...)

• Foreign Bodies & contaminants

  The analysis of foreign matter enables identification :
  - Of the morphology of contamination,
  - Of the nature of the contamination,
  - Of the source of the contamination,
  Analyses et Surface has COFRAC testing accreditation (accreditation n°1-1720 - scope available on www.cofrac.fr) for the sampling and characterization of foreign bodies (particles, fibres) by Scanning Electron Microscopy coupled with X-ray microanalysis (SEM-EDX), stereoscopy and infrared microscopy (IRTF). (...)

  Principle
  FTIR (Fourier Transformed InfraRed Spectroscopy) is based on the absorption of an InfraRed beam by a sample. Sample’s molecules rotate and vibrate at specific frequencies corresponding to discrete energy levels (vibrational modes). Transmitted radiation wavelengths and intensities are measured by the spectrometer, that allows to identify functional groups (C-C, C-H, …), and thus to identify a material. (...)
