The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenated compounds in the output stream of a gas chromatograph.

The Agilent micro-electron capture detector (micro-ECD), as part of an Agilent GC system, provides trace-level analysis of halogenated organic compounds and aromatic pollutants. Major design innovations neatly wrap ruggedness and reliability …

Jul 1, 2019 · The ECD (see Figure 1 for a schematic) is a selective detector that responds to electronegative analyte molecules capable of "capturing electrons"-more specifically, halogenated, organometallic and nitro-containing compounds.

An electron capture detector (ECD) is a device used in a GC to detect trace amounts of chemical compounds by detecting the amount of electron-absorption in a sample.

Electron-Capture Detector (ECD) ECD is a selective detector, which is highly sensitive to all electron reacting compounds containing halogen, nitro group or carbonyl group (i.e. benzodiazepines, pesticides, halogenated solvents, anesthetic gases).

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 …

For electrophilic substances, the Electron Capture Detector (ECD) is a selective, high-sensitivity detector. The ECD can detect organic halogen substances, organic metal compounds, diketone compounds, and other organic molecules.

A TCD is considered a universal detector that can measure any GC sample component having a thermal conductivity different than the carrier gas. It uses a single filament in a constant …

Gas chromatography-electron capture detector (GC-ECD) analysis is used to detect electronegative chemical species in vanishingly small concentrations. It is often used to test for …
