Table S2 Determination of Minimum Detection Limits (MDLs) for
37 cations using ICP-MS (Elan DRC II, PerkinElmer, SCIEX) from the Dong
et al. (2020) dataset “Cation Data for the East River Watershed,
Colorado. Watershed Function SFA.” doi:10.15485/1668055. The relative
standard deviation (RSD) of each measurement varies with concentrations
and detection limits, and is generally < 3% based on 3 - 5
replicate measurements for concentrations higher than detection limits.
Further details on the measurement uncertainties are included in the
published dataset.
