While a Li detection limit is quoted, the main purpose of this paper is to explore the use of the sample atmosphere (here Xe) and a binary alloy (Li in Al) to quantify trace element concentrations without calibration curve based calibrations.
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Li 370.0000 (Minimum concentration detected) 323.2700 N/A Calibration Free -10.0000--10.0000 The concentration of Li is calculated from the peak intensities (ie. without calibration curves). The method takes advantage of the ternary system (Li in Al in a Xe atmosphere) to simplify the calcs
