Calibration SOP

1. Purpose

The calibration of the Micropipette 0.1-2 µL is performed to ensure accurate volume measurements during sample preparation in the QC Chemistry Lab. This calibration controls risks associated with accuracy, patient safety, batch quality, and data integrity, thereby ensuring compliance with regulatory standards.

2. Scope

  • Asset ID: CAL-0020
  • Equipment Name/Type: Micropipette 0.1-2 µL / Micropipette
  • Department/Area: QC / Chemistry Lab
  • Process Use: Sample prep
  • Parameter: Volume
  • Range: 0.1 – 2 µL
  • Units: µL
  • Calibration Frequency: 180 days

3. Definitions

  • Calibration: The process of verifying and adjusting the accuracy of a measurement instrument.
  • Verification: The confirmation that a measurement instrument meets specified requirements.
  • Adjustment: The process of modifying a measurement instrument to bring it into compliance with specifications.
  • As Found: The condition of the instrument before calibration.
  • As Left: The condition of the instrument after calibration.
  • OOT (Out of Tolerance): A condition where the measurement falls outside the specified acceptance criteria.
  • Drift: The gradual change in the measurement output of an instrument over time.
  • Traceability: The ability to trace the measurement results back to national or international standards.
  • Measurement Uncertainty: A parameter that characterizes the range of values within which the true value is expected to lie.
  • Intermediate Check: A periodic check to ensure the instrument remains within specified tolerances between calibrations.

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 results and documentation.
  • Owner Department: Ensure equipment is available and accessible for calibration.
  • External Service Provider: Conduct external calibration 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 calibration area and equipment.
  • Check leveling of the micropipette before use.
  • Verify power supply is stable and within specifications.

7. Standards & Tools

  • Reference Standards Required: Calibration weights or standards appropriate for volume measurement.
  • Traceability Statement: Calibration is traceable to ISO17025.
  • Certificate Validity Check: Ensure calibration certificates are current and valid.
  • Standard ID Placeholders: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. The minimum number of calibration points will be five, including endpoints (0.1 µL and 2 µL) and midpoints (1 µL). It is recommended to take three replicate readings at each point to ensure accuracy.

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 the volume at specified points and record raw observations contemporaneously.
  4. Adjustment Rules: If any measurement is OOT, follow the adjustment protocol if allowed; otherwise, escalate to QA.
  5. As Left Verification: Confirm that the micropipette is within tolerance after adjustments.
  6. Labeling + Documentation Completion: Complete all required documentation and label the equipment accordingly.

10. Acceptance Criteria & Calculations

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

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

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

11. Handling OOT / Failures

  • Immediate containment: Tag the equipment and stop its use.
  • Notification & deviation initiation: Notify relevant personnel and initiate a deviation report.
  • Impact assessment trigger: Define the impact window and review affected results/batches.
  • Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
  • QA disposition placeholders: [TBD]

12. Records & Retention

  • Logbook entries must be made for each calibration event.
  • Calibration report/certificate filing must be maintained.
  • E-records if applicable: [TBD]
  • Label content requirements: calibrated date, due date, by whom, status.

Stepwise Instructions

  1. Preparation: Ensure the micropipette is clean and free from any residue.
  2. Stabilization: Allow the micropipette to stabilize at room temperature for at least 30 minutes.
  3. Performing Readings: For each test point, perform three replicates and record the observed values.
  4. Calculating Error: Calculate the error for each observed value using the formula: Error = (Observed – Ref Value) / Ref Value * 100.
  5. Evaluation: Compare the calculated error against the acceptance criteria of ±1%.
  6. Documentation: Complete the results table and ensure all data is recorded accurately.

Deviation Instruction for OOT

If any observed value is outside the acceptance criteria:

  • Stop use of the micropipette immediately.
  • Notify the supervisor and quality assurance (QA) team.
  • Open a deviation report.
  • Quarantine impacted results window: [TBD].
  • Await QA decision on further actions.
