PFAS testing is entering a new phase. With seven ultrashort-chain organofluorine compounds included in EPA Method 563, drinking water laboratories face a new set of analytical challenges, from poor chromatographic retention and background contamination to limited fragmentation.

As PFAS testing continues to expand, laboratories face increasing pressure to deliver reliable results at lower detection limits and faster turnaround times. While much of the conversation focuses on analytical methods and regulations, maintaining instrument performance and minimizing downtime are equally critical to success.

Whether supporting pharmaceutical quality control, bioanalysis, clinical research, environmental testing, or food safety applications, regulated laboratories share a common responsibility: ensuring reliable data, maintaining audit readiness, and controlling systems throughout their lifecycle. Yet when compliance discussions arise, attention often moves quickly to audits, documentation, electronic records, and standard operating procedures. These elements are essential, but they depend on a more fundamental question: Can the analytical system consistently produce reliable results?
