Short summary
Electron capture detectors (ECDs) are widely used for the detection of electron affine substances such as pesticides or chlorofluorocarbons. In this work we present a new non-radioactive ECD and investigate the analytical performance depending on the operating parameters. We achieved limits of detection for 1,1,2-trichloroethane and sevoflurane, which are comparable to radioactive ECDs. Furthermore, a pulsed collector voltage mode was implemented, leading to an extended linear range.
