Non-viable and viable monitoring is required to provide qualitative (viable active and passive air sampling) and quantitative (non-viable particle sample) data to confirm that the environment the drug product was filled within met the regulatory requirement for an aseptic process. Therefore, it is important that each application determine the risk areas of the aseptic process and place monitoring instrumentation in these locations such that ample supportive data can be provided to assure the quality of the aseptic environment and process. AST works with each one of our customer’s to properly assess the risk of the particular line design to determine the amounts of station required for the given application.
