Standard Operating Procedure for Equipment Validation of TEM/SEM in NDDS Analytics
Purpose: This SOP outlines the validation process for the Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM) used for Critical Quality Attributes (CQA) and Critical Process Parameters (CPP) in New Drug Delivery Systems (NDDS).
Scope: This procedure applies to the validation and maintenance of TEM and SEM equipment utilized in the Quality Control (QC) and Research & Development (R&D) areas for morphology characterization.
Definitions:
- Equipment Validation: A documented process that provides a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes.
- Critical Quality Attributes (CQA): Physical, chemical, biological, or microbiological properties or characteristics that should be within an appropriate limit, range, or distribution to ensure the desired product quality.
- Critical Process Parameters (CPP): A process parameter whose variability has an impact on a CQA.
Roles:
- Validation Team: Responsible for the execution and documentation of the validation process.
- Quality Assurance (QA): Ensures compliance with regulatory requirements and SOPs.
- Equipment Owner: Responsible for the maintenance and operation of the equipment.
Lifecycle Procedure:
- Design Qualification (DQ): Ensure that the equipment is designed to meet the intended use.
- Installation Qualification (IQ): Verify that the equipment is installed correctly and meets manufacturer specifications.
- Operational Qualification (OQ): Confirm that the equipment operates within specified limits.
- Performance Qualification (PQ): Ensure that the equipment performs effectively in the intended environment.
Good Documentation Practices (GDP) Controls: All documentation must be completed in real-time, signed, and dated. Records must be maintained in a controlled manner to ensure integrity and traceability.
Acceptance Criteria Governance: Acceptance criteria shall be defined in the User Requirement Specification (URS) according to Annex 11 of the GMP guidelines.
Calibration/PM Governance: The TEM/SEM must be calibrated according to the established schedule, with records maintained for all calibration and preventive maintenance activities.
Change Control Triggers: Any modifications to equipment, processes, or procedures that may impact the validated state must initiate a change control process.
Revalidation Triggers and Periodic Review: Revalidation is required every 24 months or if significant changes occur. Periodic reviews must be conducted to ensure continued compliance and effectiveness.
