Figure 2: Analysis of Ca. Top: 400 ppb of Ca natural; L2- 42Ca (grey), H3- 43Ca (orange), H6- 44Ca (dark). Bottom: interferences. Intensities for each ion are shown in small boxes against every Faraday cup. Interferences are given on the scale of 0.002 V, which is magnified 100−1000 times compared to the standard
