Analysis of ground, dried beef for their trace content of Rubidium (which is a quasi-essential element for living organisms). Beef Liver was used to spike the Rb concentration in the samples for calibrations. PLS Regression was used to improve the performance of the calibrations
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes

Element RMSE (ppm) Wavelength (nm) Calibration Method Notes
Rb 0.2200 ppm -10.0000 PLSR PLS was primarily trained using 774.5-784.82nm region around the main Rb peak at 780.10nm
