An electron capture detector is used in some gas chromatography systems.

The Auger electrons can be applied in electron capture detectors for gas chromatography.

Each channel is comprised of a pair of separation columns, flow controllers, an air selection valve, and an electron capture detector.

The detection limit for electron capture detectors is 5 femtograms per second (fg/s), and the detector commonly exhibits a 10,000-fold linear range.

After I had set up my microscope, ultra-centrifuge, electron capture detectors, and projection screen, I turned to Seth.

In cases where very low limits of detection are needed, halogenated species are frequently analyzed using an electron capture detector coupled to a gas chromatograph.

There are two ways PFTs are then detected; using an electron capture detector or negative ion mass spectrometry.

The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenal compounds in the output stream of a gas chromatograph.

Electron Capture Detector, (ECD).

All of the HATS airborne instruments make measurements using gas chromatography with electron capture detectors (ECDs).

"After the development of his electron capture detector, in the late 1960s, Lovelock was the first to detect the widespread presence of CFCs in the atmosphere."

Electron capture detector (ECD), which uses a radioactive beta particle (electron) source to measure the degree of electron capture.

Lovelock invented the electron capture detector, which ultimately assisted in discoveries about the persistence of CFCs and their role in stratospheric ozone depletion.

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.

Our particular expertise is high precision measurement requirements using electron capture detectors (ECDs) or mass spectrometric detectors (MSDs) with either packed column and capillary column gas chromatography.

The electron capture detector he invented in the 1950's produced initial measurements of dispersed traces of pesticides and ozone-destroying chlorofluorocarbons, providing a foundation for the work of Rachel Carson and for studies revealing risks to the atmosphere's protective ozone layer.

NOAA/GMD has over 130 electron capture detectors (ECDs) in use worldwide from ground based stations, balloon platforms, tall towers, ocean vessels, and airborne aircraft, manned and unmanned (many are also stored as spare units and inactive).
