Elemental Analysis Laboratories
Elemental analysis quantifies which elements a material contains and at what levels, using optical emission, X-ray fluorescence, plasma spectrometry or combustion techniques.
What does it measure?
- Alloy composition and grade verification
- Trace and residual elements
- Carbon, sulphur, oxygen, nitrogen and hydrogen by combustion or inert gas fusion
- Coating composition
When is it used?
- Positive material identification
- Certificate of conformance verification
- Restricted substance screening
- Failure analysis of wrong-material events
Sample considerations
- Surface contamination and coatings must be accounted for.
- Some techniques need a flat, prepared surface or a digested sample.

Frequently asked questions
- What is positive material identification?
- A check that a delivered part or weld is the alloy the specification requires, usually performed by X-ray fluorescence or optical emission spectroscopy.
