Electron capture detector

Schematic of an electron capture detector for a gas chromatograph with a 63Ni source.

An electron capture detector (ECD) is a device for detecting atoms and molecules in a gas through the attachment of electrons via electron capture ionization. The device was invented in 1957 by James Lovelock[1][2][3][4] and is used in gas chromatography to detect trace amounts of chemical compounds in a sample.[5][6][7]
