Figure 3.

Overall efficiency determination measurement with a 1,590 nAh stable ¹⁶⁹Tm sample and a 10,000-fold ^natEr₂O₃ excess in a presentation analog to Figure 2. Instants where the mass scans presented in Figure 4 were taken are marked with capital letters. The extracted ion current is shown with respect to the sample container temperature (top panel) over time.
