Across all experimental runs, both 𝑡 and 𝑐 ?,.@? show an overall increase with nopinone feed concentration, despite an initial decrease in 𝑐 ?,.@? . Inspecting the datasets for anomalies, the data points recorded at 𝑐 K(B),.@? ≈ 0.8 𝑚𝑜𝑙 𝑙 )+ in Run 1 were identified as outliers (highlighted by red circles on both graphs), as they lie at significantly higher values than would be expected from the dataset's trend line. This observation is in line with the fact that sampling of Run 1 had to be halted overnight after collection of the first 45 ml of permeate volume, and was resumed the next morning. Thus, the recorded increase in 𝑡 +M of Run 1 may stem from delays in re-pressurisation of the filtration cell, and/or dead volume at the cell outlet. The observed increase in 𝑐 ?,.@? of this batch may be attributed to adsorption and diffusion of nopinone through BW30 overnight, while the system was depressurised.
