Laser Induced Breakdown Spectroscopy (LIBS) Analyser
LIBS (Laser Induced Breakdown Spectroscopy) is a form of atomic optical emission spectroscopy (OES) that creates a plasma on the surface of a sample. The resulting plasma’s wavelength and intensity are collected and analyzed to determine the types and concentrations of elements present. Unlike traditional OES methods, which rely on sparks and flames to generate plasma, LIBS uses lasers. This allows for more precise control over plasma formation and enables analysis of non-conductive materials.
Benefits:
- Covers all elements (high spectral range and ability to detect carbon)
- Accurate data collection (good spectral signal to noise ratio, and improved performance in UV range)
- Minimal sample preparation required (20mm in diameter, and onboard argon purge)
- Material matching to 500+ grades (multi-library support available)
Case Study:
Customer Needs:
The objective of the analysis was to determine and compare the chemical composition of two turbine blade samples. One used and one new blade samples were tested
Cetim Matcor Findings:
Chemical analysis was conducted using laser optical emission spectrometry via a SciAps Z903LIBS analyzer. The chemical compositions of the two blades were generally similar. They were also found to be compliant to duplex stainless steel grade S32205 requirements
