| This paper describes work using both a portable (this ref) and laboratory LIBS systems (here) for the measurement of Pb in a variety of systems. The Detection system is not gated and the laser uses a passive Q-switch - making this a considerably more low-tech system than many in use. | |||||
| Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
|---|---|---|---|---|---|---|
| Pb | 100.0000 (Minimum concentration detected) | 405.7800 | 220.35 | Univariate Calibration | -10.0000--10.0000 | This result is for Pb in paint samples. Prior to analysis the paint was applied to Al plates. Two coats were used. The authors noted the likelihood of strong interferences at the 405.78nm peak, while there were less ath the 220.35nm peak. However, the sensitivity an the UV line was less. Some depth profiling also performed of Pb paint under layers of latex paint. |
