| Elemental analysis of steel scrap metals and minerals by laser-induced breakdown spectroscopy | Maria Ofelia Vieitez, Jonas Hedberg, Olli Launila, Lars-Erik Berg | Scrap Metal | Andor ICCD | Mechelle 7500 | |
| Laser: | Nd:YAG 532.0000nm 10.0000mJ 10.000Hz |

| Gate Delay: | 2.000us | ||||
| Gate Width: | 1.000us | ||||
| Analysis of Cu, Cr and Ni in scrap metal samples is performed. Severe shot to shot variation was improved by taking 10 or 50 laser pulse averages. Analysis of (cut) surface of a rock (magma) sample also performed, but no comparison concentration data is available. | |||||
| Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
|---|---|---|---|---|---|---|
| Cu | 200.0000 (Stated) | 327.3900 | N/A | Univariate Calibration | -10.0000--10.0000 | LODs not as good as expected due to large shot to shot variation in the samples |
| Ni | 5000.0000 (Stated) | 341.5000 | 346.2nm, 351.5nm, 338.1nm, 351.0 | Univariate Calibration | -10.0000--10.0000 | LODs not as good as expected due to large shot to shot variation in the samples |
| Cr | 250.0000 (Stated) | 427.5000 | N/A | Univariate Calibration | -10.0000--10.0000 | LODs not as good as expected due to large shot to shot variation in the samples |
