Notes: The run contained five certified standards (Std), seven unknown samples (Unk), two check standards (CkStd), and a full procedural blank (Blank). The drift monitor was typically analyzed more frequently at the beginning of each run. Cell ID = the position of each solution in the auto-sampler; the drift solution was kept in a 500 mL beaker. All analyses were run at least in duplicate, spaced randomly throughout the run.
