The Hidden Cause of Variability in Clinical LC-MS
When variability appears in clinical liquid chromatography-mass spectrometry (LC‑MS) data, the mass spectrometer is often the first place that laboratories look. Changes in signal intensity, quantitative drift, or failed batches are frequently attributed to detector performance, ion optics, or acquisition settings. Chromatography is often the root cause of the variability observed at the mass spectrometer.…

Is Your Organization Ready for AI Inspection?
Inspecting AI is not new to regulators. The expectations are already well-established. The key question is whether your organization can reliably demonstrate them. Written by Tracy Hibbs and Tony Sacchetti, Waters Corporation Exploring artificial intelligence (AI) and machine learning (ML) in regulated laboratories governed by Current Good Manufacturing Practices (CGMP) may be new for your...

For years, the pharmaceutical industry has anticipated regulatory clarity on the use of artificial intelligence (AI) and machine...
Reducing Risk, Rework, and Cost Through Chromatographic Stability
As clinical LC‑MS adoption continues to grow across toxicology, endocrinology, therapeutic drug monitoring, and metabolic testing, laboratories face an increasingly difficult challenge: delivering results that are not only sensitive, but routine, reproducible, and economically sustainable. While investment decisions often focus on mass spectrometry (MS) detection, experience across clinical laboratories shows that chromatography is frequently the...

Built on Control and Backed by Data: Why Vigilant Monitoring Matters in Pharma QC
Stage 3 verification: Establishing and maintaining a state of control In pharmaceutical quality control (QC), consistency should mean more than an analyst ending a shift relieved that the results were repeatable and there were no obvious failures. It should mean having enough confidence in the process, the controls, and the data to know that those...
Retention Time Stability: The Foundation of Robust Clinical LC-MS
In clinical liquid chromatography-mass spectrometry (LC‑MS), sensitivity and specificity often dominate the conversation. But behind every reliable result is a less visible parameter that determines whether workflows scale smoothly or struggle under pressure: retention time stability. As clinical laboratories increasingly rely on LC‑MS for high‑throughput, multi‑analyte testing, retention time stability has become a defining factor...
