Spectroscopic Characterisation of an Atmospheric Pressure Glow Discharge*
Recently there has been considerable interest in atmospheric discharges operating in a glow discharge mode i.e. with a spatial and sheath structure similar to that of low pressure glow discharges [1,2,3]. Here spectroscopy has been used to characterise an atmospheric pressure glow discharge (APGD), operating with either dry air, argon or helium gas flowing through the inter-electrode space and ...
متن کاملTemperature measurement of an atmospheric pressure arc discharge
The CN B 2 -X 2 + molecular emission spectrum is used to measure both the vibrational and rotational temperatures in atmospheric pressure arc jet discharges. The vibrational and rotational temperature effects on the synthetic diatomic molecular spectra were investigated from the v ,v = 0,0 band to the 5,5 band. The temperatures obtained from the synthetic spectra compared with the experimental ...
متن کاملHydrodynamic limit for an arc discharge at atmospheric pressure
In this paper we study a partially ionized plasma that corresponds to an arc discharge at atmospheric pressure. We derive an inviscid hydrodynamic/diffusion limit, characterized by two temperatures, from a system of Boltzmann type transport equations modelling that plasma problem. The original property of this system is that impact ionization is a leading order collisional process. As a consequ...
متن کاملSpatial profiles of N2 concentration in an atmospheric pressure nitrogen glow discharge
Spatial profiles of N2 concentration are measured in an atmospheric pressure nitrogen glow discharge by cavity ring-down spectroscopy. At discharge currents of ∼100 mA, we measure centreline ion concentrations on the order of 1012 cm−3, and radial profiles with radial-half-maximum of ∼1 mm. The measurements have sub-ppm concentration sensitivity, and sub-millimetre spatial resolution. Using a c...
متن کاملAtmospheric-pressure ionization and fragmentation of peptides by solution-cathode glow discharge.
Modern "-omics" (e.g., proteomics, glycomics, metabolomics, etc.) analyses rely heavily on electrospray ionization and tandem mass spectrometry to determine the structural identity of target species. Unfortunately, these methods are limited to specialized mass spectrometry instrumentation. Here, a novel approach is described that enables ionization and controlled, tunable fragmentation of pepti...
