What is Water Testing and Analysis?

Purified Water is the number one raw material used in pharmaceutical manufacturing. It is used at almost every stage of the manufacturing process from washing and cleaning to the primary ingredient in a final non-intravenous product formulation. It is produced through a multi-stage purification process usually including ion exchange and reverse osmosis. Water for injection is a further purification of pharmaceutical Purified Water via distillation, this distillation step removes bacterial endotoxins from the water. Due to the criticality of water and water systems, it is a regulatory requirement to perform routine chemical quality assessments.

Why do we do it?

The legal requirement to comply with pharmaceutical water specifications is defined in the pharmacopoeial monographs. These water specifications can be found in the following pharmacopoeias: USP, Ph Eur and JP. This literature establishes the minimum quality standards within the industry which are enforceable by the regulators. As manufacturers and services providers we have a responsibility to ensure the highest level of operational control to ensure product safety for patients.

How do we assure compliance?
