An additional example in this case showing 2 separate laser traverses conducted across a fish otolith, using simultaneous acquisition of Sr isotope data from the Nu Plasma MC-ICP-MS and trace element abundances from the Varian ICP-MS. The calculated Sr-isotope ratio is shown in red, together with a user-defined degree of smoothing shown in black. Additional time series for Ca CPS (grey) and Ba content, normalized to Ca internal standard (green) are also shown for reference. Black boxes indicate regions of interest that have been selected for output (with the height of the box representing the mean and 2s.e. of the integrated region. These boxes automatically re-calculate as the integration boundaries are edited.
