| This paper explores the analysis of a range of materials using their LIBS rig and an echelle spectrometer. Results for liquids are here, Al alloys (no wavelengths to match their LODs), powders (no LODs) and gases (link). The analysis rig for liquids involved the laser hitting the liquid surface at an angle of 15 degrees to the horizontal. A low rep rate was used to reduced splashing. | |||||
| Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
|---|---|---|---|---|---|---|
| Na | 0.5500 (Stated) | 588.9950 | N/A | Univariate Calibration | -10.0000--10.0000 | No additional details available |
| Ba | 5.0000 (Minimum concentration detected) | 455.3960 | N/A | Univariate Calibration | -10.0000--10.0000 | The authors explored improving the performance by the use of an internal standard (Sc at 431.393nm). However their conclusion was that it did not improve the performance significantly. |
