Explosives trace detectors (ETD) are explosive detection equipment able to detect explosives of small magnitude. The detection is accomplished by sampling non-visible "trace" amounts of particulates. The detection is accomplished by sampling non-visible "trace" amounts of particulates.
[citation needed] In this respect, the phrase or its abbreviation is often paired with its complement, estimated time of departure (ETD), to indicate the expected start time of a particular journey. This information is often conveyed to a passenger information system as part of the core functionality of intelligent transportation systems .

In most cases, the engineer is able to use information from the ETD to verify that the air pressure reduces and increases at the rear of the train accordingly, indicating proper brake pipe continuity. This device is said to constitute a fail-safe condition. The DPS ETD reduced labor costs, as well as the costs of the purchase and upkeep of ...
Below is a ranking of major exchange groups that offer exchange-traded derivatives (ETD), according to "Trends in ETD Trading Annual Review – 2023" published by the Futures Industry Association (FIA) on 31 January 2024. [1] [2]
Electron-transfer dissociation (ETD) is a method of fragmenting multiply-charged gaseous macromolecules in a mass spectrometer between the stages of tandem mass spectrometry (MS/MS). [1] Similar to electron-capture dissociation , ETD induces fragmentation of large, multiply-charged cations by transferring electrons to them. [ 2 ]
