That's Correct!
It's Wrong!
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 and is used in gas
chromatography to detect trace amounts of chemical compounds in a sample.
