Electron Capture Detector with Non-Radioactive Electron Source†
AbstractGas chromatographs equipped with electron capture detectors (ECD) are widely used for the analysis of electron affine substances. Achieving limits of detection in the low pptv-range, electron capture detectors are the most sensitive detectors available for such compounds. Based on their operating principle, they require free electrons at atmospheric pressure, which are usually generated by using a β--decay. However, the use of radioactive materials leads to regulatory restrictions regarding purchase, operation and disposal. Here, we present a new electron capture detector using a non-radioactive electron source, which is not subject to these limitations and offers further advantages such as adjustable and higher electron densities and energies.
