We constructed a hand-held device to efficiently trap [11C]CO2 from the cyclotron target, safely transport up to 3.7GBq (100mCi) doses to remote sites and release it without the need for a liquid cryogen. The system consists of a 180W furnace and a miniature molecular sieve trap (80-100mg; 80-100mesh 13×) placed inside a lead pig weighing 11.1kg. The overall [11C]CO2 delivery efficiency of the device is ~82% (> 99% trapping efficiency). Radiation dose rates measured at 30cm from the surface of the pig are <43.5μSv/h (5mR/h) up to 2.59GBq (70mCi).
