| Samples for analysis were pressed into pellets, and results in air, Ar and He were determined. Alternative method, involving deposition onto adhesive tape was also demonstrated. Measurements were made using double pulse LIBS. | |||||
| Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
|---|---|---|---|---|---|---|
| F | 5380.0000 (Stated) | 685.6000 | 683.4nm, 687.02nm, 690.2nm | Univariate Calibration | 0.0000-140000.0000 | Helium atmosphere on pressed pellets. Peak height was used for the calibration |
| F | 13890.0000 (Stated) | 685.6000 | 683.4nm, 687.02nm, 690.2nm | Univariate Calibration | 0.0000-140000.0000 | Air atmosphere on pressed pellets. Peak height was used for the calibration. ~3x LOD in He |
| F | 17490.0000 (Stated) | 685.6000 | 683.4nm, 687.02nm, 690.2nm | Univariate Calibration | 0.0000-140000.0000 | Argon atmosphere on pressed pellets. Peak height was used for the calibration. This is higher than Air or He LODs |
| F | 32590.0000 (Stated) | 685.6000 | 683.4nm, 687.02nm, 690.2nm | Univariate Calibration | 0.0000-140000.0000 | Ar atmosphere on sample attached to adhesive tape. Peak area was used for the calibration. Other LODs for adhesive tape were significantly higher than pressed pellets |
