Moreover, spontaneous
electron capture decay is energetically forbidden, since this is allowed for [E.sub.x] < [DELTA] - (b + [m.sub.[nu]]).
Method 608 relies upon gas chromatography with
electron capture detection (GC-ECD) to measure a targeted list.
Therefore [S.sub.eff] is calculated assuming that the
electron capture cross-sections of SRH centers and of the neutral amphoteric centers are equal ([[sigma].sub.n] = [[sigma].sup.0.sub.n]) and are 100 times larger than their hole capture cross-sections such that [[sigma].sub.n]/[[sigma].sub.p] = [[sigma].sup.0.sub.n]/[[sigma].sup.0.sub.p] = 100.

(2009), using gas chromatography with
electron capture detection (GC-ECD), found that 4,4'-DDE was frequently present in Chinese propolis than other pesticides, such as [beta]-HCH, [delta]-HCH and heptachlor.
Determination of eight synthetic pyrethroids in bovine fat by gas chromatography with
electron capture detection.
Liquid-liquid extraction and gas chromatography with an
electron capture detector was used for the determination of THMs.
Also, the gas is easily detectable with a low (0.01 ppm) minimum detection level with readily accessible portable infrared spectrophotometers or
electron capture devices.
Washington State University (Pullman, WA) has patented novel protein interaction reporter (PIR) compounds (e.g., formulas I and II), comprising at least two protein reactive moieties (e.g., N-hydroxysuccinamide), each linked to a reporter moiety (e.g., mass reporter) by a covalent labile bond that is differentially cleavable with respect to peptide bonds (e.g., by a method such as collisional activation in a mass spectrometer, activation by
electron capture dissociation, photoactivation, etc.), wherein the reporter moiety is operatively releasable from the PIR agent upon cleavage of the labile bonds, the released reporter moiety having a characteristic identifying property or label (e.g., m/z value).
Hitachi High-Technologies added
electron capture dissociation to its LC-IT-TOF system via a module on the front end of the mass spectrometer.
