Material Identification

Fast, Accurate, Affordable


Our Expertise

The most common materials testing we perform at FAI is material identification.  We start with an optical inspection and then decide on which technique to use. The most common material identification techniques are:

  • Fourier Transform Infrared Spectroscopy (FT-IR)
  • Gas Chromatography - Mass Spectroscopy (GC-MS)
  • Thermogravimetric Analysis (TGA)
  • Energy Dispersive X-Ray Spectroscopy (EDS)

What to Expect

There is no "one size fits all" approach to material identification.  We treat material identification like any other investigative process.  Some materials, such as nylon, must be identified first with FT-IR, and then with TGA or DSC to determine which type of nylon it is.  Other materials have dyes or additives that must be identified via GC-MS.  We don't identify metal alloys the same way we identify plastic co-polymers.  You can trust our scientists and technicians to recommend the most cost-effective material identification test regimen.

Case Studies


Unknown Material on Thermal Paper

Cross-section of a copper pipe with sealant and corrosion

A printer disovered crystals on their thermal paper after printing.  The crystals were leaving a visible glitter effect on the darker areas of the print.  The printing company contacted FAI to identify the unknown material.  Crystal samples were seperated from the thermal paper under a microscope and analyzed by FT-IR.  The analysis identified the material as a catalyst that was building up on rollers inside the printer.
