Abstract

In this paper, we present an electron capture detector based on low energetic X-ray ionization (X-ECD) with similar performance to radioactive electron capture detectors. The X-ECD has limits of detection in the low pptv-range and linearity over three orders of magnitude for electron-affine substances. The output signal of electron capture detectors is defined by the quantity of free electrons in a reaction region. Electron-affine substances that enter this reaction region capture the free electrons and thus reduce the amount of free electrons, which depends on substance concentration. Typically, high energetic electrons from a radioactive 63Ni source with up to 400 MBq ionizes nitrogen in the reaction region to generate a large number of free (secondary) electrons. Instead of a radioactive source, we use low energetic X-rays to ionize the nitrogen and generate free electrons. Compared to radioactive sources low energetic X-ray sources (below 30 kV and below 0.1 μSv/h 0.1m above touchable surfaces) are not or less restricted by legal regulations [5].
