Chemical and Microstructure Characterization

WRI are experts in data interpretation and well versed in analysis of both unusual samples and difficult sample matrices. We are not the typical contract lab.

  • Infrared Spectroscopy (IR) in multiple solutions, ATR and KBr pellets
  • UV-visible spectroscopy
  • Proton, carbon, phosphorous and fluorine NMR
  • High temperature Gas Chromatography for determination of alkanes up to C60 GCMS, SimDis, HTGC-FID
  • Mass Spectrometry (MS) for quantification and forensic identification
  • Differential Scanning Calorimetry (DSC) including modulated DSC, Pressure DSC
  • Thermogravimetric Analysis (TGA)
  • Atomic Force Microscopy (AFM)
  • Optical Microscopy including Fluorescence for Polymer, Polarized Light … (pictures of mesophase) (Link to Page)
