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 Dr. James E. Lovelock[1][2] and is used in gas chromatography to detect trace amounts of chemical compounds in a sample.[3][4]

These devices are different from electron detectors used in electron microscopes.
