制备注射用水采用热动力疏水器与离子交换树脂除氨的方法,制得的注射用水、含氨量完全符合中国药典1977年版规定。我院制剂室蒸馏间距锅炉房的蒸汽管道长80余米,由于管道长,锅炉产生的硬汽与金属铁管的接触面相应增大,蒸馏中含氨量增高,制得蒸馏水含氨量也增高,而且带有大量的水珠,影响注射用水的质量。为此,我们采用了热动力疏水器与离子交换树脂并用除氨法,
Preparation of water for injection Thermodynamic steam trap and ion exchange resin in addition to ammonia, water for injection, ammonia content in full compliance with the provisions of the Chinese Pharmacopoeia 1977 edition. Distillation room in our hospital distillation room boiler room steam pipe length of 80 meters long, due to the long pipe, the boiler produced hard steam and metal pipe corresponding increase in the contact surface, increased ammonia content in distilled water obtained in distilled water ammonia Increased, but also with a large number of water droplets, affecting the quality of water for injection. To this end, we use a thermodynamic steam trap and ion exchange resin with ammonia,
