Calibration SOP
1. Purpose
The calibration of the FTIR Spectrometer is performed to ensure accurate identification testing of materials, which is critical for maintaining patient safety, ensuring batch quality, and preserving data integrity. Proper calibration minimizes the risk of erroneous results that could lead to compromised product quality and regulatory non-compliance.
2. Scope
- Asset ID: CAL-0111
- Equipment Name/Type: FTIR Spectrometer / FTIR
- Department/Area: QC / Instrument Room
- Process Use: ID testing
- Parameter: Wavenumber
- Range: 400 cm-1 to 4000 cm-1
- Units: cm-1
- Calibration Frequency: 365 days
3. Definitions
- Calibration: The process of comparing a measurement instrument against a standard to determine its accuracy.
- Verification: The process of confirming that the calibration is still valid.
- Adjustment: The process of modifying the instrument to bring it into compliance with the standard.
- 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 falls outside the defined acceptance criteria.
- Drift: The gradual change in the performance of the instrument 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 associated with the result of a measurement that characterizes the range of values within which the true value lies.
- Intermediate Check: A periodic check to ensure the instrument remains within specified limits between full calibrations.
4. References
- Company Metrology SOP [TBD]
- ISO/IEC 17025 traceability via calibration certificates

5. Responsibilities
- Technician/Metrology: Perform calibration and maintain records.
- QC/QA Reviewer: Review calibration results and documentation.
- Owner Department: Ensure equipment is available and in good condition for calibration.
- External Service Provider: Conduct external calibration as per the defined schedule.
6. Safety & Preconditions
- Ensure environmental controls are in place (temperature, humidity).
- Allow for warm-up/stabilization of the instrument as per manufacturer guidelines.
- Maintain cleanliness of the instrument and surrounding area.
- Check leveling of the instrument.
- Verify power supply stability.
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 calibration points will be five, including endpoints and midpoints of the specified range (400 cm-1 to 4000 cm-1). It is recommended to take three replicate readings at each point to ensure accuracy.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the FTIR Spectrometer to warm up for the specified time.
- As Found checks and data capture: Measure the wavenumber at defined points and record the data contemporaneously.
- Adjustment rules: If any readings are OOT, follow the adjustment protocol; otherwise, escalate to QA.
- As Left verification: Re-measure the wavenumber after adjustments and record the data.
- Labeling + documentation completion: Complete all required documentation and label the instrument with calibration details.
10. Acceptance Criteria & Calculations
The acceptance criteria for the FTIR Spectrometer calibration is ±1 cm-1. The error calculation formula is:
Error = Observed Value – True Value
Pass/Fail Logic: If the absolute value of the error is within the acceptance criteria, 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: Schedule recalibration as necessary.
- QA disposition: [TBD]
12. Records & Retention
- Logbook entries: Document all calibration activities in the logbook.
- Calibration report/certificate filing: Maintain a file of all calibration reports and certificates.
- E-records if applicable: [TBD]
- Label content requirements: Include calibrated date, due date, technician name, and calibration status.
