1. Purpose
To define the procedure for qualification and monitoring of analytical column performance used in LC-MS/MS methods during BA/BE studies, ensuring consistent chromatographic behavior, reproducibility, and regulatory compliance.
2. Scope
This SOP applies to all reversed-phase analytical columns used in validated bioanalytical LC-MS/MS methods conducted for BA/BE studies in the bioanalytical department.
3. Responsibilities
- Bioanalytical Analyst: Responsible for performing column qualification and monitoring performance per method-specific
criteria.
QA Officer: Reviews column qualification records and investigates deviations or failures.
Lab Manager: Ensures traceability of column usage and qualification records.
4. Accountability
The Head of Bioanalytical Department is accountable for ensuring proper qualification, performance monitoring, and replacement of columns in accordance with this SOP.
5. Procedure
5.1 Column Receipt and Inventory
- Receive column from approved vendor with Certificate of Analysis (CoA).
- Verify physical condition and label with a unique Column ID.
- Record details in Annexure-1: Column Inventory Log including:
- Column type
- Serial number
- Dimensions
- Lot number
- Date of receipt
5.2 Initial Column Qualification
- Flush the column with recommended solvents (e.g., methanol, water, acetonitrile) to remove shipping preservatives.
- Equilibrate the column with mobile phase used in the validated method.
- Run 5 replicates of a standard solution or system suitability solution.
- Evaluate performance parameters:
- Retention time consistency (RSD ≤ 2%)
- Theoretical plates ≥ method-specified limit
- Tailing factor ≤ 2.0
- Resolution between analyte and IS ≥ 2.0
- Document results in Annexure-2: Column Qualification Report.
5.3 Routine Column Usage and Monitoring
- Log every use of the column including:
- Date of use
- Run ID
- Number of injections
- Analyst name
- Monitor performance weekly or every 500 injections (whichever comes first).
- Check chromatograms for:
- Peak symmetry
- Baseline noise
- Drift or pressure changes
- Document observations in Annexure-3: Column Usage and Monitoring Log.
5.4 Column Regeneration and Disposal
- Regenerate columns by back-flushing with strong solvent if performance declines.
- If regeneration fails or column is damaged:
- Mark column as ‘Out of Use’
- Dispose as per lab’s hazardous waste SOP
- Record in Annexure-4: Column Disposition Log
