How does gas chromatography work? Explore the principles of GC separation, the main analytical steps, and the roles of the injection port, carrier gas, column, and detector.

A practical guide to GC column troubleshooting. Learn how to identify and resolve peak tailing, loss of resolution, ghost peaks, baseline drift, sensitivity issues, and retention time shifts.

Injecting water into a GC system can cause backflash, poor vaporization, detector issues, and stationary phase degradation. Learn how to minimize these risks with the right column and injection setup.

Comprehensive two-dimensional gas chromatography (GC×GC) greatly expands separation power for complex mixtures. Explore its principles, applications, limitations, and future trends.

How small should measurement uncertainty be? Eurachem explains how target measurement uncertainty helps laboratories ensure results are fit for purpose and support reliable decisions.

Learn how GC-MS combines gas chromatography and mass spectrometry for sensitive compound separation, identification, quantification, and structural analysis across a wide range of applications.

How should laboratories handle a significant measurement bias? This Eurachem leaflet explains when correction is justified and how an uncorrected bias may affect measurement uncertainty.

Dr. Lee Polite explains the fundamentals of GC/MS through memorable analogies, making one of analytical chemistry's most powerful techniques easy to understand.
