a Extraction efficiencies for microfluidic extraction of Ga-68 from various Zn(NO3)2 solutions in 0.01 M HNO3. The flow rate was 40 µL/min for both solutions. b Extraction efficiencies for microfluidic extraction of Ga-68 from 2 M Zn(NO3)2 solutions with varying nitric acid concentrations. The flow rate was 40 µL/min. c Back-extraction efficiencies for microfluidic back-extraction of Ga-68 into 2 M and 6 M HCl with varying flow rates. d Zn contamination in final HCl solutions after back-extraction. Error bars represent one standard deviation of the mean (n = 3)
