Shewhart control charts for cellular uptake determinations. The upper control limit (UCL) and lower control limit (LCL) were computed according to ISO 8258 from eleven independent uptake experiments (SW480 cells, 2 h exposed to 50 μM KP1019), in which accuracy (top) and precision (bottom) are controlled. corresponds to the average cellular ruthenium amount of independent experiments, is the average standard deviation of parallel experiments.
