1. An FDG synthesizer, which comprises: a labeling reaction resin column in which (i) target water containing fluoride ion and (ii) a triflate solution are passed through said labeling reaction resin column, said labeling reaction resin column comprising a column filled with a polymer-supporter phase-transfer catalyst resin, for trapping the fluoride ion contained in the target water, and wherein a labeling reaction is performed between the thus trapped fluoride ion and the triflate, and  a hydrolysis reaction vessel for receiving a reaction intermediate product obtained from the labeling reaction, and wherein a hydrolysis reaction is performed by the addition of a strong acidic aqueous solution or a strong alkaline aqueous solution.  said polymer-supported phase-transfer catalyst resin comprises a phosphonium salt fixed to a polystyrene resin.  a labeling reaction resin column in which (i) target water containing fluoride ion and (ii) a triflate solution are passed through said labeling reaction resin column, said labeling reaction resin column comprising a column filed with a polymer-supporter phase-transfer catalyst resin for trapping the fluoride ion contained in the target water, and wherein a labeling reaction is performed between the thus trapped fluoride ion and the triflate, and  a cation-exchange resin column for receiving a reaction intermediate product obtained from the labeling reaction, and wherein a hydrolysis reaction is performed by bringing the reaction intermediate product into contact with a cation-exchange resin adjusted to an H.sup.+ cation-exchange resin in the cation-exchange resin column.  the cation-exchange resin column has a heating means and a flow rate control means for controlling the flow of said reaction intermediate product which contains an organic solvent, and in said cation-exchange resin column, said reaction intermediate product containing said organic solvent obtained from said labeling reaction is heated, to evaporation-eliminate said organic solvent by the heating means in the cation-exchange resin column, and at the same time, said reaction intermediate product after the elimination of said organic solvent is brought into contact with the cation-exchange resin adjusted to an H.sup.+ cation-exchange resin in the cation-exchange resin column to perform said hydrolysis reaction.  (a) a cartridge labeling reaction resin column, (b) a cartridge cation-exchange resin column, and (c) a disposable cartridge base into which passageways and switchover valves for communicating said labeling reaction resin column with said cation-exchange resin column, are incorporated; in said cartridge labeling reaction resin column (i) target water containing fluoride ion and (ii) a triflate solution are passed through, said cartridge labeling reaction resin column comprising a disposable column filled with a polymer-supported phase-transfer catalyst resin, said cartridge labeling reaction resin column being one-touch-releasably attachable to said disposable cartridge base, for trapping the fluoride ions contained in the target water, and wherein a labeling reaction between the thus trapped fluoride ion and the triflate take place; and said cartridge cation-exchange resin column comprising a disposable column filled with a cation-exchange resin adjusted to an H.sup.+ cation-exchange resin, said cartridge cation-exchange resin column being one-tough-releasably attachable to said disposable cartridge base, and wherein a reaction intermediate product obtained from said labeling reaction is brought into contact with said cation-exchange resin adjusted to said H.sup.+ cation-exchange resin in said cation-exchange resin column to perform a hydrolysis reaction.  each of said switchover valves includes a three-way cock therein. 2. The FDG synthesizer as claimed in claim 1, wherein: 3. An FDG synthesizer, which comprises: 4. The FDG synthesizer as claimed in claim 3, wherein: 5. The FDG synthesizer as claimed in claim 4, wherein the heating means for the cation-exchange resin column heats the cation-exchange resin column from 90 to 150.degree. C., and wherein the flow rate control means controls the flow of the reaction intermediate product from 0.5 to 1.5 cc/minute. 6. An FDG synthesizer, which comprises: 7. The FDG synthesizer as claimed in claim 6, wherein: 8. The FDG synthesizer as claimed in claim 6, wherein the synthesizer body comprises a means for driving the switchover valves and a means for heating the cartridge labeling reaction resin column and the cartridge cation-exchange resin column. 9. The FDG synthesizer as claimed in claim 6, wherein the passageways comprise a teflon tube. 10. The FDG synthesizer as claimed in claim 6, wherein the passageways comprise a polypropylene tube.
