Fig. 4From: Automated synthesis and quality control of [99mTc]Tc-PSMA for radioguided surgery (in a [68Ga]Ga-PSMA workflow)High performance liquid chromatography (HPLC) chromatogram of the radiodetector. The retention time of unbound [99mTc]pertechnetate is 2.5 min. The retention time of [99mTc]Tc-PSMA is between 10 and 15 min, with different peaks accounting for different protonation statesBack to article page
