Numerical calculations were conducted to study a hybrid model of the near-cathode plasma in a newly developed PLES detector for gas chromatography. The results demonstrate the formation of narrow peaks, which represent the spectra of fast electrons generated by Penning ionization from helium impurities like Ar, N-2, O-2, and CO2.
Numerical calculations based on a hybrid model of near-cathode plasma (negative glow) of a short glow discharge have been performed to describe processes occurring in a newly developed PLES (plasma electron spectroscopy) detector for gas chromatography. The formation of narrow peaks is demonstrated, which are the spectra of fast electrons generated by Penning ionization from atoms and molecules of helium impurities, such as Ar, N-2, O-2, and CO2.
