Course information
HPLC Data Extraction, Interpretation & ISO 17025 Reporting
A practical guide to transforming raw HPLC chromatograms into defensible, audit-proof analytical reports compliant with ISO/IEC 17025 standards.
AUDIENCE: HPLC Analysts & QC Specialists · LEVEL: Intermediate · TRAINING TYPE: Virtual Interactive Training
In a regulated testing laboratory, generating high-quality HPLC data is only half the battle. Most audit findings and non-conformities occur during data processing, integration, quantitative calculations, and result reporting.
This training connects raw chromatographic signals to regulatory decision-making, providing analysts with the tools required to ensure data integrity, maintain ALCOA+ compliance, and draft technical reports that withstand external scrutiny.
Key Takeaway: Most laboratory non-conformities are data-related, not instrumental. Master the complete analytical workflow from raw detector signals to compliant reporting.

COURSE CONTENT
⚖️ ROLE OF DATA IN ISO/IEC 17025-COMPLIANT HPLC
Positioning data within the analytical workflow: sample → instrument → data system → report → decision
Root causes of analytical non-conformities: instrumental vs. data handling errors
Legal and regulatory implications of poor data governance
ISO/IEC 17025 clause-to-practice mapping: data integrity, technical records, measurement uncertainty, reporting, and non-conforming work
💻 HPLC DATA ACQUISITION AND RAW DATA MANAGEMENT
Defining raw HPLC data: chromatograms, detector signals, instrument parameters, sequence tables, and audit trails
Data acquisition best practices: sequence design (blanks, standards, QC, samples), injection order rationale, avoiding carryover and drift
Electronic Data Systems (CDS): user access controls, metadata preservation, audit trail review, and archival expectations
🔬 CHROMATOGRAM INTERPRETATION
Fundamental metrics: baseline stability, noise, drift, peak height vs. area, and chromatographic resolution
Peak identification criteria: retention time (RT) matching, relative retention time (RRT), peak purity (PDA/DAD), and matrix recognition
Interpretation pitfalls: identifying ghost peaks, co-elution, baseline disturbances, and complex matrix interferences
⚙️ PEAK INTEGRATION AND DATA PROCESSING
Integration fundamentals: automatic vs. manual integration parameters and criteria
Technical justification and compliance expectations for manual integration
ISO/IEC 17025 requirements for re-integration and reprocessing: change traceability, audit trail recording, supervisor review, and batch consistency
📈 CALIBRATION, QUANTIFICATION, AND CALCULATIONS
Calibration models: external standard, internal standard, and standard addition techniques
Curve evaluation: linearity assessment, working ranges, weighting factors, and acceptance criteria
Quantitative calculations: response factors, dilution factors, recovery adjustments, and final concentration determinations
🧪 METHOD PERFORMANCE CHARACTERISTICS & QC
Precision and trueness: repeatability, intermediate precision, and bias evaluation
Detection and quantification limits: signal-to-noise (S/N) and statistical LOD/LOQ estimation
Measurement uncertainty: identifying sources, top-down vs. bottom-up approaches, and reporting conventions
System Suitability Testing (SST): retention time, resolution, tailing factor ($T_f$), and theoretical plate count ($N$)
Ongoing Quality Control: handling blanks, spikes, control charts, and executing CAPA for QC failures
🛡️ DATA INTEGRITY (ALCOA+) & ISO 17025 REPORTING
Implementation of ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available)
Audit readiness: assembling data packages and anticipating auditor queries
Mandatory elements of an ISO/IEC 17025 test report: sample identification, method references, measurement uncertainty, decision rules, and statements of conformity
Matrix-specific reporting practices: pharmaceuticals, food/feed, environmental, and biological testing
