1. A process in which an inner shell electron is captured by the nucleus of its own atom.

The mass number is unchanged, but the atomic number is decreased by one and this process is accompanied by the emission of a neutrino.

2. A radioactive decay process in which an atomic nucleus with an excess of protons draws an electron into itself, creating a neutron out of a proton and thus decreasing the atomic number by one.

Often the resulting nucleus is unstable and achieves stability by giving off a gamma ray.

electron capture detector, electron-capture detector
1. A device used in gas chromatography, in which carrier gas molecules flowing through the ionization chamber are radiated and low-energy electrons are formed.

Certain compounds entering the chamber have an affinity for these electrons, and this decrease in electrons is recorded for component identification.

2. An extremely sensitive gas chromatography detector that is a modification of the argon ionization detector, with conditions adjusted to favor the formation of negative ions.
3. An item of laboratory equipment used coupled to a gas chromatograph for the detection and quantification of very minute amounts halogenated organic compounds.
