PIXL Instrument Chart Sample

Figure 2. This figure demonstrates that the PIXL instrument detects important trace elements (red) at 10’s ppm. Insert: Rb, Sr, Y, Zr are clearly detected due to the lack of interfering excitation lines at 13–17 keV in PIXL (continuum subtracted using a modeled fit to Bremsstrahlung).
