Which method is mainly used in the GMP WFI system in china to prepare water for injection
Most of the GMP WFI system in china all use distillation, which is of course related to the quality status of domestic reverse osmosis devices. The Pharmacopoeia requires that the water source for the preparation of water for injection by distillation in the GMP WFI system in china should be purified water, so the raw water must be purified by filtration, deionization and other processes before it can be used.
The GMP WFI system in china mainly includes main modules such as water for injection preparation, circulating storage, dynamic distribution and process control. It is worth noting that in the GMP WFI system in china, different distilled water machines have different requirements for source water. Different types of distilled water machines in the GMP WFI system, due to differences in performance, can use purified water, deionized water and deeply softened water as source water, and then prepare water for injection that meets the standard.
The distillation method of the GMP WFI system in china has a good removal effect on inactive organic and inorganic substances in raw water, including suspended solids, colloids, bacteria, viruses and pyrogens and other impurities. Note that the structure, performance, metal material, operation method and raw water quality of the distilled water machine in the GMP WFI system in china will affect the quality of the water for injection.
