Purpose

This SOP outlines the procedures for the validation of the Laser Diffraction Particle Size Analyzer used in QC/R&D for particle size distribution analysis.

Scope

This procedure applies to the validation of the Laser Diffraction Particle Size Analyzer within the QC/R&D departments. It includes all phases of equipment validation: DQ, IQ, OQ, and PQ.

Definitions

  • DQ: Design Qualification
  • IQ: Installation Qualification
  • OQ: Operational Qualification
  • PQ: Performance Qualification
  • CSV: Computerized System Validation

Roles

  • Validation Team: Responsible for conducting and documenting validation activities.
  • Quality Assurance: Ensures compliance with validation protocols and regulatory requirements.
  • Laboratory Personnel: Operate the equipment and provide input for validation activities.

Lifecycle Procedure

The lifecycle of the Laser Diffraction Particle Size Analyzer includes the following phases:

  • Design Qualification (DQ): Assess equipment design against user requirements.
  • Installation Qualification (IQ): Verify installation and configuration.
  • Operational Qualification (OQ): Validate operational parameters.
  • Performance Qualification (PQ): Confirm performance under actual conditions.

GDP Controls

Good Documentation Practices (GDP) must be adhered to throughout the validation process, ensuring all records are accurate, complete, and traceable.

Acceptance Criteria Governance

Acceptance criteria for the validation of the Laser Diffraction Particle Size Analyzer will be governed by the User Requirement Specification (URS) and Annex 11 of the relevant regulations.

Calibration/PM Governance

The Laser Diffraction Particle Size Analyzer must undergo regular calibration and preventive maintenance in accordance with the manufacturer’s guidelines and internal SOPs.

Change Control Triggers

Any changes to the equipment, software, or operational procedures will trigger a change control process to assess the impact on validation status.

Revalidation Triggers and Periodic Review

Revalidation is required every 12 months, or when significant changes occur. Periodic reviews will assess the need for revalidation based on equipment performance and compliance.
