This paper explores the analysis of a range of materials using their LIBS rig and an echelle spectrometer. Results for liquids (link), 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
Kr 50000.0000 (Minimum concentration detected) 811.2900 N/A -10.0000--10.0000 Authors note that no optimisation was performed and the 5% Kr in N2 is well resolved - hence actual detection limit is significantly lower. Result included as LODs for Kr are so rare in the literature.
