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 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...
متن کاملAttenuation of single-tone ultrasound by an atmospheric glow discharge plasma barrier
Propagation of 143 kHz ultrasound through an atmospheric pressure glow discharge in air was studied experimentally. The plasma was a continuous dc discharge formed by a multipin electrode system. Distributions of the gas temperature were also obtained in and around the plasma using laser-induced Rayleigh scattering technique. Results show significant attenuation of the ultrasound by the glow di...
متن کاملThe development of uniform atmospheric pressure glow discharges: appearance of stable glow discharge in air, argon, oxygen and nitrogen at atmospheric pressure using a 50 Hz source (S Okazaki et al 1993 J. Phys. D: Appl. Phys. 26 889)
The development of atmospheric pressure plasmas (APPs) for chemical synthesis, mat erials processing, environmental cleanup and now for biotechnology has been continually challenged by the desire, and the need, to produce uniform glow discharges. A scaling law in low temperature plasmas states that if ionization occurs only from the ground state, the gas density N is constant, and the E/N (ele...
