The structural integrity of metals is a key factor in the performance of any company's operations. In addition to ensuring optimal production, a 100% metal structure avoids any risk of major problems within companies. However, on some occasions, these parts can be damaged, putting operations at risk, and threatening the company's other assets.

Although each company has its preventive maintenance plans, it is often impossible to determine with standard methods the failures, or the structures that can potentially cause difficulties in the short or medium term. In these cases, it is necessary to rely on innovative methodologies such as optical emission spectroscopy. You should know what it consists of, and the great benefits it will bring to your company.

What is Optical Emission Spectroscopy (OES)?

This is a metal chemical analysis that allows detection, study, and monitor the growth of films of materials by atomic layer deposition (ALD). That is, it allows to determine if in a given metallic structure there is any other type of unwanted metal or other material that could cause troubles, even if it is in an imperceptible thin film.

Keep in mind that each element has a spectrum with a different wavelength. Optical emission spectrometers apply electricity to the area under study to excite the electrons of the different elements present in the area. Once the electrons are activated, each element in the structure emits its spectrum, which is picked up by the detectors. These photomultiplier detectors measure the presence and concentration of each element, thus making it possible to detect structural anomalies in metals.

OES applications

These are some of the tasks you can perform in your company using OES technology:

  • Cabron analysis, including presence and concentrations, and carbon equivalent calculation.
  • Structural inspections of both new construction and structures in use.
  • Chemical verification of products, to ensure that they comply with standards
  • Identification of the presence of incorrect metals
  • Ensure the integrity of welds
  • Evaluate corrosion potentials
  • Identify areas or equipment susceptible to sulfidation
  • Chemical testing of components for verification of API 578 materials.

How is OES Implemented?

For the inspection of a part or surface by OES, the use of an OE spectrograph is essential. This device emits the arc-shaped beam of electricity that allows the excitation of electrons and the subsequent measurement of the spectra present in the sample. Keep in mind that this is specialized equipment of moderate to high risk, so the wisest thing to do is to have the support of a specialized top-of-the-line service such as the one offered by ACUREN.

Besides, it should also be understood that the technology has some limitations. The spectrometer is a bulkier instrument than other analysis equipment, and its use is limited to being able to enter the area or part to be analyzed. So it will not be possible to use it in places with limited space.
