WFI-/ Pure steam generation
Water for injection (WFI) is the most critical raw material for parenteral pharmaceutical production. As such the qualities at the point of use are regulated in the different international pharmacopeia´s such as USP, EP, JP. The EP is permitting distillation as the only method to produce WFI. Although some pharmacopeia´s allow alternative production technologies, distillation is the technology of choice and industry standard for the generation of WFI.
For pure steam the USP has set the quality requirement for condensate of the pure steam identical to WFI quality.
