Design Qualification Protocol for Tangential Flow Filtration System
Meta Description: This document outlines the Design Qualification Protocol for the Tangential Flow Filtration System, focusing on its application in NDDS for liposomes and lipid nanoparticles.
Tags: Equipment Validation, DQ, TFF, NDDS, Liposomes, Lipid Nanoparticles
Objective
The objective of this Design Qualification (DQ) protocol is to ensure that the Tangential Flow Filtration (TFF) System is designed and installed in compliance with user requirements and regulatory standards for its intended use in buffer exchange and concentration processes.
Scope
This protocol applies to the Tangential Flow Filtration System utilized in the R&D and Production areas for the development of NDDS, specifically liposomes and lipid nanoparticles.
Responsibilities
- Validation Team: Responsible for the execution of the DQ protocol, documentation, and reporting.
- Quality Assurance: Responsible for reviewing and approving the DQ protocol and ensuring compliance with regulatory requirements.
- Engineering: Responsible for the installation and maintenance of the TFF System.
Prerequisites
- Completion of User Requirement Specification (URS).
- Installation of TFF System in the designated R&D/Production area.
- Training of personnel on the operation of the TFF System.
Equipment Description
The Tangential Flow Filtration (TFF) System is designed for the separation and concentration of liposomes and lipid nanoparticles. It operates based on the principle of tangential flow, utilizing a membrane to achieve efficient filtration.
