Title: Flame ionization detection under elevated pressures
Abstract: The pressure dependence of the background ionization current in the flame ionization detector has been measured, as well as the ionization efficiency of methane and the relative molar responses of various types of compound at pressures ranging within 1–25 atm. All the above parameters show a strong dependence on pressure; at pressures higher than about 10 atm the ionization efficiency becomes practically independent of pressure. The exceedingly high variability of the response to halogen-containing compounds, depending on the pressure, could be utilized as a principle of selective detection.
