  • METHOD FOR PREPARING A SALINE SOLUTION COMPRISING [13N] NH4 + AND USE OF A DEVICE
    Publication number: 20090324493
    Abstract: The invention relates to a method for preparing a saline solution comprising [13N]NH4+. The method comprises following steps: preparing [13N]NH3 gas, transporting [13N]NH3 gas to a diffusion chamber, to a first side of a semipermeable membrane, transporting sterile saline solution to the diffusion chamber, to a second side of a semipermeable membrane, allowing the mixing of [13N]NH3 gas that has penetrated the semipermeable membrane with the saline solution on the second side of the semipermeable membrane, whereby saline solution comprising [13N]NH4+ is obtained, and directing the saline solution comprising [13N]NH4+ out from the diffusion chamber. The invention relates also to use of a device for preparing a radiolabelled saline solution for preparation of a saline solution comprising [13N]NH4+.
