Meaning
Atomic emission spectroscopy utilizing short laser pulses provides rapid chemical analysis of solid samples without the need for extensive sample preparation. In this technique, laser induced breakdown spectroscopy focuses a high-energy laser pulse onto the surface of a material to generate a micro-plasma. By measuring the light emitted by this plasma, the system determines the chemical composition of the target.
Performance Capability
Portable devices run this analysis in real-time on the factory floor. While laser induced breakdown spectroscopy is faster than wet chemical methods, it displays greater measurement variability due to surface roughness. To achieve repeatable results, operators must clean the surface before testing.
Inspection Procedure
Quality assurance departments employ these portable scanners to audit the material grades of incoming metallic bars and sheets. Workers use laser induced breakdown spectroscopy to verify that the carbon content of incoming steel matches the mill certificate. This rapid sorting prevents the incorrect material from entering the production line, which reduces scrap rates.
Enforcement Action
Chinese market regulation administrations have adopted this laser technology for field audits of recycling facilities and scrap steel processing hubs. When inspectors suspect the mixing of prohibited hazardous waste or non-standard alloys, they deploy laser induced breakdown spectroscopy for immediate on-site screening. If the scanning shows concentrations of regulated elements above legal limits, the inventory is seized and sent to an accredited laboratory for formal compliance testing.
