Performance Qualification Protocol for Analytical Balance in QC Laboratory
Objective: To validate the performance of the Analytical Balance in the QC Laboratory to ensure accurate weighing of samples and standards.
Scope: This protocol applies to the Analytical Balance used in the QC Laboratory for weighing applications, impacting product quality directly.
Responsibilities:
- Validation Team: Execute the protocol and document results.
- Quality Assurance: Review and approve the protocol and results.
- Laboratory Personnel: Operate the Analytical Balance as per SOPs.
Prerequisites:
- Completion of Installation Qualification (IQ).
- Calibration of the Analytical Balance as per the manufacturer’s specifications.
- Training of personnel on the use of the Analytical Balance.
Equipment Description:
The Analytical Balance is a precision instrument designed for accurate weighing of samples and standards in the QC Lab. It features high sensitivity and is equipped with an audit trail function to ensure data integrity.
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| PQ-AB-01 | Verify accuracy using calibrated weights. | Weight measurements must be within ±0.001g of the true value. | Calibration report and weight measurement records. |
| PQ-AB-02 | Assess repeatability by weighing the same sample multiple times. | Standard deviation must not exceed 0.002g. | Data from repeatability tests. |
| PQ-AB-03 | Evaluate linearity across the operating range. | Linearity must be within ±0.002g across specified weights. | Linearity test results. |
| PQ-AB-04 | Check for drift over time. | No drift greater than ±0.001g over a 24-hour period. | Drift test results. |
| PQ-AB-05 | Audit trail verification. | All entries must be logged and retrievable. | Audit trail report. |
Detailed Test Cases:
- Test Case 1: Verify accuracy using calibrated weights. Weigh a series of calibrated weights and record the measurements. Compare against the true values.
- Test Case 2: Assess repeatability by weighing the same sample 10 times and calculating the standard deviation.
- Test Case 3: Evaluate linearity by weighing different weights across the balance’s range and plotting the results.
- Test Case 4: Monitor drift by weighing a standard weight at intervals over 24 hours.
- Test Case 5: Review the audit trail for completeness and accuracy, ensuring all actions are logged.
Deviations: Any deviations from the acceptance criteria must be documented and investigated. A root cause analysis should be performed, and corrective actions should be implemented.
