Abstract
A method and device for reducing positron emitter isotope labeled COto positron emitter isotope labeled CO generally includes introducing a volume of positron emitter isotope labeled COinto a first heated reaction vessel comprising a metal oxide, such as Iron (II) Oxide such that the COis reduced to CO upon contact with the Iron (II) Oxide. The volume is then transferred to a second reaction vessel to remove any un-reacted CO, preferably, via a soda-lime trap. The volume is then transferred to a target, e.g., a storage vessel or subject. The COincludes one of [C] or [O]. The first reaction vessel is, preferably, heated to a temperature of between 900 and 1000° C., and more preferably, to between 925 and 975° C., and even more preferably, to approximately 950° C. Preferably, the Iron (II) Oxide powdered and has a particle size of about −10 mesh.
