1. Purpose
This SOP outlines the procedure for the qualification of High-Performance Liquid Chromatography (HPLC) systems to ensure suitability for analytical applications. The qualification confirms that the system performs reliably and complies with
applicable pharmacopeial and regulatory requirements.
2. Scope
This SOP applies to all new and existing HPLC systems used in Analytical Method Development (AMD) for research, validation, and quality control activities in the pharmaceutical environment.
3. Responsibilities
- Analytical Chemist: Performs the qualification tests and records results.
- Engineering Department: Assists in utility and hardware-related verifications.
- QA Officer: Reviews qualification reports and authorizes qualification status.
- IT Administrator: Validates software configuration and data backup systems.
4. Accountability
The Head of Analytical Method Development is accountable for ensuring all HPLC systems are qualified prior to use and requalified as per requalification schedule or upon major maintenance.
5. Procedure
5.1 Qualification Phases
- Design Qualification (DQ): Verify that selected HPLC system specifications meet intended purpose.
- Installation Qualification (IQ): Confirm proper installation of hardware, software, and utilities.
- Operational Qualification (OQ): Evaluate operational controls, safety features, and software interface.
- Performance Qualification (PQ): Validate system performance using known standards.
5.2 Installation Qualification (IQ)
- Check utility connections (power, LAN, printer, etc.).
- Verify hardware serial numbers and configurations against purchase order.
- Install software with appropriate user rights and audit trail enabled.
- Fill Annexure-1 for IQ documentation.
5.3 Operational Qualification (OQ)
- Start the HPLC system and check baseline noise and drift.
- Test autosampler movement, injection precision, and pump gradient accuracy.
- Verify detector wavelength accuracy and linearity using caffeine solution.
- Log observations in Annexure-2.
5.4 Performance Qualification (PQ)
- Inject system suitability standard as per USP/EP guidelines.
- Calculate %RSD, tailing factor, and theoretical plates.
- Repeat over 3 days to confirm robustness and repeatability.
- Document results in Annexure-3.
5.5 Requalification Triggers
- Major repairs or component replacements
- Software upgrades or reinstallation
- Long periods of inactivity (>6 months)
- Audit observations or validation failures
5.6 Documentation and Approval
- Compile all annexures into a single qualification report.
- Submit for QA review and approval.
- Update the instrument qualification master list.
