A client operating an existing filling line sought to optimize the nitrogen purge process to reduce headspace oxygen levels to 2%. In addition, frequent line stoppages created the need to identify and reject vials with elevated oxygen levels that had lost their nitrogen headspace during these interruptions.

Read this case study to learn how a purging process qualification study was conducted using rapid, non-destructive headspace oxygen analysis in an at-line setup, with samples measured immediately after removal from the filling line.
