Description: Supplementary Figure 1. The impact of a bubble in the electrode flow cell on peak areas, peak ratios and calibration graphs: (a) the peak areas for Cu (■) and Pb (), and the Cu/Pb stripping ratio (●); (b) the calibration graphs generated using Cu/Pb stripping ratios in white wine (●) and model wine (■); and (c) the calibration graphs generated using Cu stripping times in white wine (●) and model wine (■). For (a), the order of analysis is: determination (det.) 1-3, model wine + 0.080 mg/L Cu; det. 4-6, model wine + 0.04 mg/L Cu; det. 7-9, model wine + 0.020 mg/L Cu; det. 10-12, white wine + 0 mg/L Cu; det. 13-15, white wine + 0.040 mg/L Cu; and det. 16-18, white wine + 0.080 mg/L Cu. The bubble event occurred from analysis numbers 11 to 14.
