Patent ID: 7667011

Claim:
A method for labeling synthesis, comprising: (a) Providing a UV reactor assembly comprising a high pressure reaction chamber, a UV spot light source with a light guide, wherein the light guide is used to provide photo irradiation of a reaction mixture through a window in the reaction chamber, (b) dissolving or reacting a base with water, (c) adding a solution of alkyl or aryl iodides to the solution of step (b) to give a reagent volume to be labeled, (d) introducing a 11 C-monoxide enriched gas-mixture into the reaction chamber of the UV reactor assembly via the gas inlet, (e) introducing at high pressure said reagent volume into the reaction chamber via the liquid inlet, (f) turning on the UV spot light source and waiting for a predetermined time while the labeling synthesis occur, and (g) collecting the labeled acid from the reaction chamber.
