ABSTRACT:
When using an electron capture detector for the molecular identification of electrophilic compounds, the sensitivity of the detector is made reproducible by controlling the voltage or frequency of the pulses applied to it to maintain a reference current whose set value is produced automatically by the device after determination of the characteristics of the state of the detector, namely a so-called saturation current CM and a so-called spontaneous current CS, according to a law of proportionality between these two currents.
