Exova Singapore routinely provides the laboratory based and on-site chemical analysis of the steels that comprise pipelines, equipment and other structures where the material’s identification is critical in maintaining the design and service life.

Optical Emission Spectroscopy (OES)

Sometimes called a spark chemical test — is a fast and reliable method for testing the chemistry of metallic materials.

Exova’s Singapore laboratory currently has two Optical Emission Spectroscopy machines to serve our clients with important data for material characterization.

Chemical Testing Capabilities Include:

Stationary OES

• Laboratory based testing for consistent chemical analysis of materials submitted for destructive testing.

Portable OES

• On-site testing solution for positive identification (PMI) of materials using methods which can also provide results for carbon and nitrogen in steels.

Positive Material Identification (PMI)

Exova has a strong history of supporting our client in both the laboratory and at the customer’s location.

PMI allows for the chemical analysis and identification of metallic materials already in their service life.

This non-destructive means of analysis allows for materials to remain in-service without disruption to production, processing or loss of structural integrity.

With Exova’s portable SPECTROTEST OES, on-site PMI becomes a convenient solution for chemical analysis providing results such as carbon in low-alloy steels and nitrogen in duplex steels which other methods can’t match.
