3. Definitions

  • Calibration: The process of verifying and adjusting the accuracy of a measurement instrument.
  • Verification: Confirming that an instrument meets specified requirements.
  • Adjustment: Modifying an instrument to bring it into compliance with specifications.
  • As Found: The condition of the instrument prior to any adjustments.
  • As Left: The condition of the instrument after adjustments have been made.
  • OOT (Out of Tolerance): A condition where the instrument’s performance does not meet specified acceptance criteria.
  • Drift: The gradual change in an instrument’s performance over time.
  • Traceability: The ability to verify the history, location, or application of an item by means of documented recorded identification.
  • Measurement Uncertainty: A parameter that characterizes the range of values within which the true value is asserted to lie.
  • Intermediate Check: A verification process conducted between calibrations to ensure continued accuracy.

4. References

  • Company Metrology SOP [TBD]
  • ISO/IEC 17025 traceability via calibration certificates
  • ALCOA+ principles

5. Responsibilities

  • Technician/Metrology: Perform calibration and maintain records.
  • QC/QA Reviewer: Review calibration records and ensure compliance.
  • Owner Department: Ensure equipment is available and properly maintained.
  • External Service Provider: Conduct external calibrations as required.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm up and stabilize as per manufacturer guidelines.
  • Maintain cleanliness of the work area and equipment.
  • Check leveling of the equipment before use.
  • Verify power supply is stable and within specifications.

7. Standards & Tools

  • Reference Standards Required: [TBD]
  • Traceability Statement: ISO17025
  • Certificate Validity Check: Ensure all reference standards are within validity period.
  • Standard ID Placeholders: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: 5 points including endpoints (2 µL and 20 µL) and midpoints.
  • Replicate readings at each point: 3 repeats as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the micropipette to stabilize in the calibration environment.
  3. As Found checks and data capture: Measure and record the volume at each calibration point.
  4. Adjustment rules: If OOT is found, follow adjustment procedures if allowed; otherwise, escalate to QA.
  5. As Left verification: Measure and record the volume again after any adjustments.
  6. Labeling + documentation completion: Ensure all records are completed and labeled appropriately.

Record raw observations contemporaneously to ensure data integrity (ALCOA+).

10. Acceptance Criteria & Calculations

The acceptance criteria for the calibration of the micropipette is ±1%. The error calculation formula is:

Error (%) = (Observed Value – True Value) / True Value × 100

Pass/Fail Logic: If the error falls within ±1%, the calibration passes; otherwise, it fails.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Notify QA and initiate deviation report.
  • Impact assessment trigger: Define impact window and review of affected results/batches.
  • Recalibration after repair/adjustment: Ensure recalibration is performed before returning to service.
  • QA disposition placeholders: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities.
  • Calibration report/certificate filing: Maintain records for audit purposes.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, by whom, and status.
