Document Number: OQ-LD-001
Version: 1.0
Effective Date: [Insert Date]
Prepared By: [Insert Name]
Approved By: [Insert Name]
Objective
The objective of this Operational Qualification (OQ) protocol is to validate the Laser Diffraction Particle Size Analyzer to ensure it meets specified performance criteria for particle size distribution analysis in the QC/R&D areas.
Scope
This protocol applies to the Laser Diffraction Particle Size Analyzer used for particle size distribution analysis in the Quality Control and Research & Development departments. It covers the validation of critical parameters including accuracy, repeatability, and audit trail.
Responsibilities
The following personnel are responsible for executing this protocol:
- Validation Team: Execute the OQ protocol and document results.
- Quality Assurance: Review and approve the protocol and results.
- Equipment Owner: Ensure equipment is maintained and calibrated.
Prerequisites
The following prerequisites must be completed prior to executing this OQ protocol:
- Installation Qualification (IQ) must be completed and approved.
- Calibration of the Laser Diffraction Particle Size Analyzer must be current.
- Staff must be trained on the operation of the equipment.
Equipment Description
The Laser Diffraction Particle Size Analyzer is an instrument designed to measure particle size distribution using laser diffraction technology. The analyzer is critical for ensuring product quality and compliance with specifications.
Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| OQ-01 | Verify accuracy using standard reference materials. | Results must fall within ±5% of expected values. | Calibration report and test results. |
| OQ-02 | Conduct repeatability tests over multiple runs. | Standard deviation must be < 2%. | Test results summary. |
| OQ-03 | Verify audit trail functionality. | All actions must be logged and retrievable. | Audit trail report. |
Detailed Test Cases
Test Case OQ-01:
1. Prepare standard reference materials.
2. Run the analyzer and record results.
3. Compare results with expected values.
Test Case OQ-02:
1. Conduct at least 5 consecutive measurements on the same sample.
2. Calculate the standard deviation of the results.
Test Case OQ-03:
1. Access the audit trail feature.
2. Verify that all user actions are logged properly.
Deviations
Any deviations from the protocol must be documented and justified. Approval from Quality Assurance is required for any deviations.
