Standard Operating Procedure for the Validation of Osmometer in NDDS Analytics

Purpose: This SOP outlines the validation process for the Osmometer used in routine osmolality testing for parenteral NDDS, ensuring compliance with regulatory requirements and product quality.

Scope: This procedure applies to the validation, qualification, and maintenance of the Osmometer in the Quality Control (QC) area for all parenteral NDDS products.

Definitions:

• Osmometer: An instrument used to measure the osmolality of solutions.
• Critical Quality Attribute (CQA): A physical, chemical, biological, or microbiological property that should be within an appropriate limit to ensure desired product quality.
• Critical Process Parameter (CPP): A process parameter whose variability can impact a CQA.

Roles:

• Quality Assurance (QA): Responsible for oversight and approval of validation activities.
• Quality Control (QC): Responsible for conducting routine testing and ensuring equipment is properly validated.
• Validation Team: Responsible for executing validation protocols and documenting results.

Lifecycle Procedure:

1. Design Qualification (DQ): Ensure the Osmometer meets user requirements and regulatory standards.
2. Installation Qualification (IQ): Verify that the equipment is installed according to specifications.
3. Operational Qualification (OQ): Confirm that the equipment operates within predetermined limits.
4. Performance Qualification (PQ): Validate that the Osmometer performs effectively in routine testing.

Good Documentation Practices (GDP) Controls: All records must be maintained in accordance with GDP, including equipment logs, calibration certificates, and validation documentation.

Acceptance Criteria Governance: Acceptance criteria will be governed by the User Requirements Specification (URS) and Annex 11 guidelines, ensuring all critical parameters are met.

Calibration/PM Governance: The Osmometer must be calibrated according to manufacturer specifications and undergo preventive maintenance (PM) as per the established schedule.

Change Control Triggers: Any change in equipment, process, or product that may affect the osmolality testing must initiate a change control process.

Revalidation Triggers and Periodic Review: Revalidation is required annually or upon any significant change to equipment or processes. Periodic reviews will be conducted to assess the continued validity of the validation status.
