A fully automated apparatus for repeated production of 13NH3 from proton-bombarded water has been developed. Its operation sequence consists of the introduction of NaOH, the bombarded water containing 13NO3- and TiCl3 into a reaction vessel, the distillation of 13NH3 formed by the reduction of the 13NO3-, and the washing of the vessel for the next sequence. The NaOH and TiCl3 are added as 4 ml of saturated solution and 4 ml of 10% aqueous solution, respectively, and halogen lamps are used as the heat source for the distillation. By this apparatus, 13NH3 can be produced automatically and repeatedly in a radiochemical yield of 80-90% within 10 min from the EOB.
已开发出一种用于从质子轰击水重复生产¹³NH₃的全自动装置。其操作顺序包括将NaOH、含有¹³NO₃⁻的轰击水和TiCl₃引入反应容器，蒸馏由¹³NO₃⁻还原形成的¹³NH₃，以及清洗容器以进行下一轮操作。NaOH和TiCl₃分别作为4毫升饱和溶液和4毫升10%水溶液加入，卤钨灯用作蒸馏的热源。通过该装置，从EOB起10分钟内可自动且重复地生产¹³NH₃，放射化学产率为80 - 90%。
