Calibration SOP

1. Purpose

The calibration of the LC-MS is performed to ensure the accuracy of mass accuracy measurements, which is critical for maintaining patient safety, ensuring batch quality, and preserving data integrity. Accurate measurements are essential to prevent erroneous results that could impact product quality and regulatory compliance.

2. Scope

  • Asset ID: CAL-0124
  • Equipment Name/Type: LC-MS
  • Department/Area: QC / Instrument Room
  • Process Use: MS analysis
  • Parameter: Mass accuracy
  • Range: 0 – 2000 amu
  • Units: amu
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of verifying and adjusting the accuracy of an instrument against a standard.
  • Verification: The process of confirming that an instrument meets specified requirements.
  • Adjustment: The act of modifying an instrument to bring it into compliance with specified standards.
  • 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 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 asserted to lie.
  • Intermediate Check: A periodic check of an instrument’s performance 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 in good condition for calibration.
  • External Service Provider: Conduct external calibration as per the calibration type.

6. Safety & Preconditions

  • Environmental controls: Ensure temperature and humidity are within specified limits.
  • Warm-up/Stabilization: Allow the instrument to stabilize for [TBD] minutes before calibration.
  • Cleanliness: Ensure the instrument and surrounding area are clean and free from contaminants.
  • Leveling: Verify that the instrument is properly leveled.
  • Power Supply Checks: Confirm that the power supply is stable and within specifications.

7. Standards & Tools

  • Reference Standards: [TBD]
  • Traceability Statement: Calibration will be traceable to ISO17025.
  • Certificate Validity Check: Ensure all reference standards are within their validity period.
  • Standard ID: [TBD]

8. Calibration Strategy

The calibration will follow an As Found then As Left logic. The minimum number of test points will be five, including endpoints and midpoints. 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 LC-MS to warm up for [TBD] minutes.
  3. As Found Checks and Data Capture: Measure the mass accuracy at defined points and record the data contemporaneously.
  4. Adjustment Rules: If any measurement is OOT, follow the adjustment protocol; if adjustments are not allowed, escalate to QA.
  5. As Left Verification: Re-measure the mass accuracy to confirm adjustments are within acceptance criteria.
  6. Labeling + Documentation Completion: Complete all required documentation and label the equipment with calibration details.

10. Acceptance Criteria & Calculations

The acceptance criteria for mass accuracy is ±0.5 amu. The error calculation formula is:

Error = Observed Value – True Value

Pass/Fail Logic: If the absolute value of the error is less than or equal to 0.5 amu, the calibration passes; otherwise, it fails.

Rounding Rule: [TBD]

11. Handling OOT / Failures

  • Immediate Containment: Tag the equipment and cease use until resolved.
  • 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 after any adjustments.
  • QA Disposition: [TBD]

12. Records & Retention

  • Logbook Entries: Document all calibration activities in the logbook.
  • Calibration Report/Certificate Filing: Maintain a file of calibration reports and certificates.
  • E-Records: [TBD]
  • Label Content Requirements: Include calibrated date, due date, technician name, and status.
