| This online article summarises a number of different applications of the SciAps Hand Held LIBS analyser. In this result, 4 samples were used in the calibration. 20 analysis spots were made on each sample, and the total measurement took 18s. While undoubtedly a promotional piece, this gives some of the few available detection limit figures for handheld LIBS devices. | |||||
| Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
|---|---|---|---|---|---|---|
| Rh | 30.0000 (Calibration Curve Slope) | -10.0000 | N/A | Univariate | 10.0000-225.0000 | 20 analysis spots, taking 6 seconds for the full analysis. The authors indicate that this is preliminary data. |
| Pd | 100.0000 (Calibration Curve Slope) | -10.0000 | N/A | Univariate | 250.0000-1550.0000 | 20 different laser spots used in the analysis. Analysis time, approximate 6s. |
| Ce | 100.0000 (Calibration Curve Slope) | -10.0000 | N/A | Univariate | 4000.0000-50000.0000 | 20 different laser spots used in the analysis. Analysis time, approximate 6s. Calibration concentrations estimated from Fig 2d. |
| Pt | 300.0000 (Calibration Curve Slope) | -10.0000 | N/A | Univariate | 450.0000-2000.0000 | 20 different laser spots used in the analysis. Analysis time, approximate 6s. Calibration concentration range estimated from Fig 2b. |
