CHEMICAL ANALYSIS

Techniques

Bulk chemical analyses on metals and materials are available using the following techniques:

  • Optical Emission Spectroscopy
  • Combustion (LECO) for C & S
  • Atomic Absorption

Surface analyses are available by SEM/EDS.

Phase identification is available by X-ray Diffraction.
