| abstract |
The invention relates to a microfluidic reactor having a reaction chamber configured as an annular passage (22). The invention provides that segments (25) are formed in the annular passage (22) such that due to a succession of inlets (23) and outlets (24), an alternation between the process fluids (A and B) can take place. According to the invention, additional particles (27) can be provided in the annular passage (22), which circulate in the annular passage, and which can be used for absorbing and desorbing ions, for example. In this way, the ions in question can be removed from the process fluid (A) and transferred to the process fluid (B), for example. In a further claimed method, the reactor according to the invention can be used to realize 18 F - ions from the water enriched therewith, and to convey said ions to a solvent like acetonitril, for example. In further progression, a radiopharmacon (FDG, for example) can be produced from the 18 F - ions. |
