This paper describes 2 main applications of Double Pulse LIBS - Pb in Soil, and S in Coal using a purpose built instrument. Samples were prepared by mixing powdered sulphur with coal samples, then pressing into pellets in a hand press |
Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
---|---|---|---|---|---|---|
S | 20000.0000 (Minimum Concentration Detected) | 545.3800 | N/A | Univariate | -10.0000--10.0000 | As the detection system only went from 200-800nm, the usual S peaks could not be used. Instead the weaker 545.38nm peak was used for calibrations |
S | 1000.0000 (Minimum Concentration Detected) | 191.4700 | N/A | Univariate | -10.0000--10.0000 | Special CCD detector (with improved quantum efficiency in the UV) used for this measurement. Standard instrument only has 200-800nm range. |
