Figure 6
Comparison of SR-µXRF accuracy against the sensitivity of SR-µXRF for selected elements, showing that SR-µXRF is low for elements when SR-µXRF sensitivity is low. The dashed line is the ideal slope of unity, indicating 1:1 agreement between SR-µXRF and ICP-MS concentrations. Error bars in the x direction denote the range (n = 2) in SR-µXRF sensitivity between synchrotron experiments when available. For the y axis, the error bars are the 95% confidence intervals for the slope. |
