From the robustness study that was performed, it is evident that Mean Absolute Deviation and Standard Mean Error values for the three samples (SAMPL8-16, SAMPL8-17 and SAMPL8-14) that contained replicate measurements were very similar and demonstrated that the measured drug concentrations of those three samples were repeatable. However, it should be noted that these replicates were sampled from the same sample vial, which may imply that the MAD and SME are measures related to the sampling capabilities of the robotic platform rather than the actual samples themselves. To improve upon the uncertainty analysis, replicate sample vials should be prepared, and replicate measures should be drawn from each individual vial.
