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 |
