A current is produced between two electrodes in the detector supplied with a potential difference and this is monitored as a continuous. The electron capture detector is used in detecting electron-absorbing components in the output stream of a gas chromatograph.
A (beta-ray) radio active source which can. 1 It is a device for use in gas chromatography that can detect tiny amounts of chemical compounds in the atmosphere and elsewhere. The electron capture detector (ECD) is a selective detector for electro-negative compounds, especially halogens. A (beta-ray) radio active source which can ionize the carrier gas is located in the detector. The electron capture detector (ECD) was invented in 1957, by Dr. Linear Dynamic Range: Greater than 10 4 with lindane. The electron capture detector (ECD) is a selective detector for electro-negative compounds, especially halogens. Produced by Agilent Technologies, and boasting reliability combined with unprecedented sensitivity and accurate quantitation of samples containing compounds with unknown concentrations, it is able to offer detection in the ranges from femtograms to nanograms per microliter.īy bolstering our line-up in this key area, Quinta are confident in repeating the last twenty years of history by remaining a fully certified top-class services provider to the global pharmaceutical industry. The 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. This Refurbishment is another of the services Ellutia can offer.Įllutia also offers a service whereby ownership of detectors that are no longer required can be transferred to Ellutia they will then be assessed for reuse or disposal.įor more information on these services please click here.The team at QUINTA-ANALYTICA are very pleased to announce delivery of our latest innovative piece of technology in the form of specialized selective gas chromatography detectors, allowing us to offer even greater selectivity and sensitivity to our clients and partners.īy increasing our ability to detect compounds in matrices further, our new micro-electron capture detector provides trace-level analysis of halogenated organic compounds and aromatic pollutants, and is the most sensitive ECD on the market. The test samples are then sent to Ellutia for analysis and report.ĮCDs can be contaminated by dirty samples and require cleaning, the legal requirements mean that this must only be carried out by suitably qualified personnel in a registered laboratory.

ELECTRON CAPTURE DETECTOR FULL
It is a legal requirement that the detectors are leak tested (wipe tested) to detect radioactive contamination of the surface at intervals of between one and three years depending upon local regulations. Ellutia supply a convenient leak test kit containing full instructions and materials to perform the test. Ellutia Ltd is licensed to provide a range of services designed to help users of these devices remain within the law. A sample absorbs the negative electron ions which causes changes in the current being measured by an ECD.
Offers extreme sensitivity down to 10 ppt.
The ECD may be thermostated from ambient to 375C. Ni-63, a radioactive beta emitter, ionizes the gas used in a GC. The Buck Electron Capture Detector can be operated with either nitrogen or argon-5 methane (P5) makeup gas, and nitrogen, P5, or helium carrier (as long as the helium flow is less than 10 milliliters per minute). Electron Capture Detectors contain a radioactive source and so are controlled by legislation. electron capture detector (ECD) is a device used in a GC to detect trace amounts of chemical compounds by detecting the amount of electron-absorption in a sample.
