Fig. 15: ToF-SIMS profiles obtained for barium from pristine and altered SO2 dealkalized samples of glass B (B_CEMb), C (C_CEMb) and O (O_CEMb).
From: Surface treatments on commercial glasses: durable impact on the retention of lead, barium and boron

The results from the pristine slabs are presented with solid lines and the results from the altered slabs are presented with dashed lines. b Is a zoom on the superficial region of (a). The signals are normalized to the total intensity and to the pristine glass signal, as described by Eq. (3).
