The term electronic civil disobedience and hacktivism may be used synonymously, although some commentators maintain that the difference is that ECD actors don’t hide their names, while most hacktivists wish to remain anonymous. Some commentators maintain that ECD uses only legal means, as opposed to illegal actions used by hacktivists.
ECD produces significantly different types of fragment ions (although primarily c- and z-type, b-ions have been identified in ECD [9]) than other MS/MS fragmentation methods such as electron-detachment dissociation (EDD) (primarily a and x types), [10] [11] [12] collision-induced dissociation (CID) (primarily b [13] and y type) and infrared ...
Electron-capture dissociation (ECD) was developed in 1998 to fragment large proteins for mass spectrometric analysis. [7] Because ECD requires a large amount of near-thermal electrons (<0.2eV), originally it was used exclusively with Fourier transform ion cyclotron resonance mass spectrometry (FTICR), the most expensive form of MS instrumentation.

Depending on the analyte, an ECD can be 10-1000 times more sensitive than a flame ionization detector (FID), and one million times more sensitive than a thermal conductivity detector (TCD). An ECD has a limited [clarification needed] dynamic range and finds its greatest application in analysis of halogenated compounds. [9]
