Introduction Recently in our laboratory we needed a reliable and relatively simple source of aqueous solutions of [11C]CO2. We examined various methods of trapping [11C]CO2 gas both in solution and on ion exchange resins, followed by elution into aqueous phase. We favor simple methods that have high...
