Operational Qualification Protocol for Tangential Flow Filtration System
Meta Description: This document outlines the Operational Qualification (OQ) protocol for the Tangential Flow Filtration System used in the R&D and Production of Liposomes and Lipid Nanoparticles.
Tags: Equipment Validation, OQ, TFF System, Liposomes, LNP, R&D, Production
Objective
The objective of this Operational Qualification (OQ) protocol is to verify that the Tangential Flow Filtration (TFF) System operates according to its intended use and meets the specified requirements for buffer exchange and concentration of Liposomes and Lipid Nanoparticles.
Scope
This protocol applies to the Tangential Flow Filtration System utilized in the R&D and Production areas for the formulation of NDDS involving Liposomes and Lipid Nanoparticles. The OQ will cover critical parameters including TMP, flow, membrane integrity, temperature, and audit trail.
Responsibilities
- Validation Team: Responsible for executing the OQ protocol and documenting results.
- Quality Assurance: Responsible for reviewing and approving the protocol and results.
- Equipment Owner: Responsible for ensuring equipment is calibrated and maintained prior to OQ execution.
Prerequisites
- Completion of Installation Qualification (IQ).
- Calibration of the TFF System as per manufacturer specifications.
- Availability of necessary materials and resources for testing.
Equipment Description
The Tangential Flow Filtration (TFF) System is designed for buffer exchange and concentration of Liposomes and Lipid Nanoparticles. It operates by using a semi-permeable membrane to separate particles based on size, allowing for efficient purification processes.

| OQ-TFF-04 | Check operating temperature during filtration. | Temperature within specified limits. | Temperature logs. |
| OQ-TFF-05 | Verify audit trail functionality. | Audit trail records all operations accurately. | Audit trail report. |
Detailed Test Cases
Test Case OQ-TFF-01: TMP Measurement
Procedure: During operation, measure the Transmembrane Pressure (TMP) at specified intervals. Document the readings.
Acceptance Criteria: TMP should remain within the specified operating range as defined in the User Requirement Specification (URS).
Evidence: Recorded TMP values will be attached to the final report.
Test Case OQ-TFF-02: Flow Rate Measurement
Procedure: Measure the flow rate of the TFF system during operation to ensure it meets specifications.
Acceptance Criteria: Flow rate should be consistent with operational specifications.
Evidence: Flow rate data logs will be included in the final report.
Test Case OQ-TFF-03: Membrane Integrity Test
Procedure: Perform a membrane integrity test to confirm that the membrane is functioning correctly.
Acceptance Criteria: Membrane integrity must be confirmed as per the defined standards.
Evidence: Integrity test results will be documented.
Test Case OQ-TFF-04: Temperature Check
Procedure: Monitor and record the operating temperature during the filtration process.
Acceptance Criteria: Operating temperature must remain within the specified limits.
Evidence: Temperature logs will be attached to the final report.
Test Case OQ-TFF-05: Audit Trail Verification
Procedure: Review the audit trail functionality to ensure that all operations are accurately recorded.
Acceptance Criteria: The audit trail must accurately reflect all operations performed on the TFF system.
Evidence: The audit trail report will be included in the final documentation.
Deviations
Any deviations from the acceptance criteria must be documented and reviewed by the Quality Assurance team. A root cause analysis may be required for critical deviations.
