Atmospheric-pressure glow discharge

One particular example of what may be called a gas-liquid discharge microreactor is the work of Baba et al. (2006, 2007), who have demonstrated the generation of an atmospheric pressure glow-discharge plasma in contact with liquid paraffin, using a capacitively coupled plasma method. The choice for paraffin has two reasons no hydroxyl group present (which is thought to capture electrons, as is the case in water)... 

When the system pressure of such a luminous gas phase is raised, it is generally considered that the electron temperature, 7)., ion temperature, T, and temperature of neutral species, Tji approach an equilibrium state (thermal equilibrium), and the plasma becomes hot at round lOOtorr. On the other hand, there is a type of glow discharge that is termed atmospheric-pressure glow discharge, which is claimed to be atmospheric low-temperature plasma. Obviously, such low-temperature plasma...

A schematic of a glow discharge tube is shown in Figure 4.6. Ions that are formed in an atmospheric pressure glow discharge can be used as an ion source for IMS. In one case, this ion source was used to characterize perfume odors. In another study, the sensitivity toward m-xylene was enhanced compared to the Ni and CD sources, and the dynamic range was extended to three orders of magnitude. ...

This new, active, and extremely attractive field of MS has room for new ideas and improvements. In this sense, atmospheric pressure glow discharges (APGD) can generate a much larger number and wider variety of reagent ions than other chemical ionization techniques [29], and hence is tunable for a larger variety of applications.

The effect of atmospheric pressure glow discharge (APG) plasma treatment on CO2 permeability and selectivity of poly(dimethylsiloxane) membranes was investigated in detail. The selectivity of CO 2 over CH4 was remarkably improved at low power input conditions (i.e. a few watts), and showed a maximum as a function of treatment time. The maximum CO2/CH4 selectivity obtained was 76, and the permeance of CO2...

Atmospheric chemical plasma treatment systems are typically non-thermal, atmospheric-pressure, glow-discharge plasma systems that generate uniform and homogenous treatments. The level of surface tension and iongevity of treatment are both typically higher than air plasma treatment effects, and similar in treatment effect to flame plasmas.
