Calibration SOP
1. Purpose
The calibration of the CO2 Incubator CO2 Sensor is performed to ensure accurate measurement of CO2 levels within the specified range. This calibration controls risks associated with accuracy, patient safety, batch quality, and data integrity, thereby ensuring compliance with Good Manufacturing Practices (GMP) in the Biologics department.

3. Definitions
- Calibration: The process of configuring an instrument to provide a result for a sample within an acceptable range.
- Verification: The process of confirming that an instrument is functioning correctly.
- Adjustment: The act of modifying an instrument to bring it within specified limits.
- 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 measurement exceeds the acceptance criteria.
- Drift: The gradual change in an instrument’s output 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 check performed between calibrations to ensure continued accuracy.
4. References
- Company Metrology SOP [TBD]
- ISO/IEC 17025 traceability via calibration certificates

5. Responsibilities
- Technician/Metrology: Perform calibration and document results.
- QC/QA Reviewer: Review calibration documentation for compliance.
- Owner Department: Ensure equipment is available and 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 specifications.
- Maintain cleanliness of the calibration area and equipment.
- Check leveling of the equipment.
- Verify power supply stability and functionality.
7. Standards & Tools
- Reference Standards: [TBD]
- Traceability Statement: ISO17025
- Certificate Validity Check: Ensure all reference standards are within their validity period.
8. Calibration Strategy
Calibration will follow an As Found then As Left logic. The minimum number of points for calibration will be five, including endpoints and midpoints of the specified range (0%CO2 to 20%CO2). Each point should have three replicate readings to ensure accuracy.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the CO2 Incubator to stabilize for the recommended period.
- As Found checks and data capture: Measure CO2 levels and record initial readings.
- Adjustment rules: If any readings are OOT, follow the adjustment protocol; if not allowed, escalate to QA.
- As Left verification: Re-measure CO2 levels to confirm adjustments.
- Labeling + documentation completion: Complete all required documentation and label the equipment accordingly.
Record all raw observations contemporaneously to ensure data integrity (ALCOA+).
10. Acceptance Criteria & Calculations
Acceptance criteria for the CO2 sensor calibration is ±0.5%. The error calculation formula is:
Error = (Observed Value – True Value) / True Value × 100%
Pass/Fail logic: If the error falls within ±0.5%, the calibration passes; otherwise, it fails.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and stop its use.
- Notification & deviation initiation: Notify QA 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 include all calibration activities.
- Calibration report/certificate filing should be maintained for audit purposes.
- E-records if applicable: [TBD]
- Label content requirements: calibrated date, due date, by whom, status.
