1. Purpose
This Standard Operating Procedure (SOP) provides detailed instructions for the verification of analytical methods prior to their use in routine analysis, especially when the method has been transferred from another laboratory or
2. Scope
This SOP applies to all analysts, supervisors, and quality reviewers involved in the analytical method verification (AMV) activities in the Analytical Method Development (AMD) department. It covers methods for active pharmaceutical ingredients (APIs), excipients, raw materials, in-process samples, and finished pharmaceutical products.
3. Responsibilities
- Analyst: Performs method verification experiments and records data as per protocol.
- Section Head: Reviews raw data and final results; initiates CAPA if necessary.
- QA Representative: Ensures protocol approval, compliance with SOPs, and archiving.
4. Accountability
The Head of Analytical Method Development is accountable for reviewing and approving all verification reports, and for ensuring proper documentation, traceability, and data integrity.
5. Procedure
5.1 Prerequisites for Verification
- Ensure receipt of the original validated method along with method transfer protocol or justification for method adaptation.
- Review previous validation data to identify critical parameters and known variability.
- Ensure instruments used are qualified and calibrated.
5.2 Planning and Documentation
- Develop a verification protocol outlining:
- Scope and objectives
- Test parameters and acceptance criteria
- Materials and equipment used
- Data evaluation strategy
- Submit protocol to QA for review and approval before execution.
5.3 Verification Parameters
Verification must address critical attributes, typically including but not limited to:
- System Suitability: Plate count, tailing factor, resolution
- Precision: Repeatability (n=6), %RSD ≤ 2%
- Accuracy: % Recovery at 3 concentration levels (80%, 100%, 120%)
- Specificity: Blank, placebo, and matrix interference
- Linearity: 5 levels minimum, R² ≥ 0.998
5.4 Execution
- Perform verification as per approved protocol under similar conditions of intended use.
- Conduct triplicate runs where required for accuracy and precision parameters.
- Record chromatograms, spectra, calculations, and observations clearly.
5.5 Data Evaluation
- Evaluate data against predefined acceptance criteria.
- If results fall outside the criteria, perform deviation investigation and RCA.
- Summarize findings in the Verification Report (Annexure-2).
5.6 Approval and Archival
- Submit final report for QA review and sign-off.
- Ensure report includes all raw data, calculations, instrument logs, and analyst sign-offs.
- Store approved report in AMD Document Control Archive.
