Calibration SOP
1. Purpose
The calibration of the CO2 Analyzer (Incubator) is performed to ensure accurate CO2 control within the incubator, which is critical for maintaining optimal cell culture conditions. This calibration mitigates risks associated with inaccurate CO2 levels that could compromise patient safety, batch quality, and data integrity.

- Department/Area: Biologics / Cell Culture
- Process Use: CO2 control
- Parameter: CO2
- Range: 0%CO2 to 20%CO2

3. Definitions
- Calibration: The process of verifying and adjusting the accuracy of an instrument.
- Verification: The confirmation that an instrument meets specified requirements.
- Adjustment: The process 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 instrument’s measurements fall outside the specified 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 expected to lie.
- Intermediate Check: A periodic assessment of an instrument’s performance between calibrations.
4. References

5. Responsibilities
- Technician/Metrology: Perform calibration and document results.
- QC/QA Reviewer: Review calibration documentation and results.
- Owner Department: Ensure equipment is available and maintained.
- 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’s instructions.
- Maintain cleanliness of the equipment and surrounding area.
- Check leveling of the equipment.
- Verify power supply stability.
7. Standards & Tools
- Reference Standards Required: [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 and As Left logic:
- Minimum number of points: At least 5 points including endpoints and midpoints within the range of 0%CO2 to 20%CO2.
- Replicate readings at each point: 3 repeats as a best practice.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the CO2 Analyzer to stabilize in the operating environment.
- As Found checks and data capture: Measure CO2 levels at defined points and record results contemporaneously.
- Adjustment rules: If OOT is detected, follow adjustment protocols; otherwise, escalate to QA.
- As Left verification: Confirm that all adjustments bring the instrument within acceptance criteria.
- Labeling + documentation completion: Complete all required documentation and label the equipment appropriately.
10. Acceptance Criteria & Calculations
The acceptance criteria for the CO2 Analyzer 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 is considered a pass; otherwise, it is a fail.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and stop use.
- Notification & deviation initiation: Notify QA and initiate deviation procedures.
- Impact assessment trigger: Define impact window and review of affected results/batches.
- Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
- QA disposition placeholders: [TBD]
12. Records & Retention
- Logbook entries: Document all calibration activities.
- Calibration report/certificate filing: Maintain records of calibration certificates.
- e-Records if applicable: [TBD]
- Label content requirements: Include calibrated date, due date, technician name, and status.
