Figure 4
Normalized absorbance at 595 nm during the cleaning process. Cleaning performance using the model contaminants. The inset shows the area between 6 and 180 s. (a) Buffer, (b) 30% MPD, (c) 15%(w/v) PEG3350, (d) 1 M (NH4)2SO4. For (a)–(c) n = 3 and for (d) n = 6. Error bars represent the standard deviation. |
