How does electron capture detector work
WebElectron capture is one form of radioactivity. A parent nucleus may capture one of its orbital electrons and emit a neutrino. This is a process which competes with positron emission and has the same effect on the atomic number. Most commonly, it is a K-shell electron which is captured, and this is referred to as K-capture. WebThe electron capture detector is an example of a selective detector. As shown in Figure 12.33, the detector consists of a β-emitter, such as 63 Ni. The emitted electrons ionize the …

WebIt fits in the palm of your hand and has the ability to detect invisible particulates in the air. The electron capture detector (ECD) was created by James Lovelock, who built the prototype at his kitchen table. In the late 1950s Lovelock was a young researcher attempting to determine the damage done to living cells when frozen. WebThe iConnect Electron Capture Detector features a miniaturized cell equipped with a purged, removable anode, designed to maximize robustness towards the matrix effect while guaranteeing fast peak detection and maximum sensitivity. MDL: Less than 4.5 fg/s lindane. Linear Dynamic Range: Greater than 10 4 with lindane.

The ECD is a selective detector used in the analysis of halogenated compounds (pesticides and herbicides) and oxygenated compounds (phthalates and ketones). The ECD detection mechanism is based on the depletion of the background signal between two electrodes in the presence of compounds that absorb …
WebThe detector consisted of a small chamber with two electrodes parallel to each other and a radioactive source, usually 63 Ni, placed close to the cathode to ionize the carrier gas. A …
