Fig. 3From: Improved GMP-compliant multi-dose production and quality control of 6-[18F]fluoro-L-DOPAAn example of a typical chromatogram of FDOPA -L performed with UPLC-UV and radioactivity detector (upper). Green is UV and the black line is RA signal. Notice that because the different detector position there is a delay in RA-signal.
