To establish a method for rapid detection of Kryptofix 2.2.2 in
18
F-labeled PET radiopharmaceuticals.
Methods:
Pretreated thin layer chromatography (TLC) silica gel plates
saturated with iodoplatinate reagent
were the medium. The
18
F-labeled imaging agents and standard solutions were applied on the pretreated plate and the spots were visually compared.
Results:
There was a dark blue circle or ring in the center of the spot for standard solution. The similar spot would appeare if the test solution had Kryptofix 2.2.2.
Conclusion:
The method is simple
rapid
sensitive
repeatable and suitable for the detection of Kryptofix 2.2.2 in
