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.
