Fig. 4From: Ethanol effects on 68Ga-radiolabelling efficacy and radiolysis in automated synthesis utilizing NaCl post-processingRadioHPLC chromatograms representing a synthesis without (a) and with additional ethanol (b) in the reaction mixture. Sample collection took place directly after final formulation. In region 1 (8.12 ± 0.13 min) radiolysis by-products can be found. The signal at 8.66 ± 0.08 min in region 2 indicates the productBack to article page
