GC-FID | Gas Chromatography Flame Ionization Detector

The Flame Ionization Detector (FID) stands out as the predominant detection method in Gas Chromatography (GC) for identifying and measuring organic compounds.
Technical Notes

Electron Capture Detector | GC-ECD

The Electron Capture Detector (ECD) in gas chromatography (GC) is employed to detect compounds capable of undergoing electron capture reactions, displaying heightened sensitivity towards electronegative elements like halogens, as well as select nitrogen and oxygen compounds.

Nitrogen-Phosphorus Detector (NPD)

The Nitrogen-Phosphorus Detector (NPD) is a specialized instrument employed in Gas Chromatography (GC) for the discriminative detection of compounds containing nitrogen and phosphorus.

Pulsed Flame Photometric Detector (PFPD)

Learn about the 2 modes of Pulsed Flame Photometric Detectors.
Technical Notes

Thermal Conductivity Detector - Gas Chromatography

The Thermal Conductivity Detector (TCD) stands as one of the earliest detectors employed in Gas Chromatography (GC) for the detection and quantification of components within a gas sample.
