	abstract = {A jet-assisted glow discharge emission source has previously been shown to suffer from self-absorption when the viewing axis is orientated in line with the support gas flow. This problem can be alleviated by rotating the viewing axis 90-degrees so that the absorption path length is significantly reduced; however, in viewing side-on, line-of-sight measurements of the plasma plume can be accomplished no closer than 25 mm from the sample surface due to geometry limitations. At this axial distance from the sample, the plume shows no Ar 11 emission, which differentiates it from the negative glow. Furthermore. evidence was found that the plume possesses features similar to flowing afterglows: energy is transported from the negative glow to the plume through argon metastable atoms. The collision of two metastable argon atoms produces ionization to the ground state of the argon ion, deactivation to the ground state of the argon atom and an energetic electron (7.32-7.68 eV) which is capable of exciting sputtered atoms. A strong correlation is observed between the square of the argon metastable population and the emission intensity for Cu I and Zn I as the jet flow rate is manipulated.},

	abstract = {Comparisons have been made between three types of glow discharge with regard to analytical performance. These glow discharge types include a Grimm-type glow discharge, a jet-assisted glow discharge viewed axially to the jet-assisted plasma plume and the same discharge viewed laterally 25 mm from the sample surface where its characteristics are sufficiently different to warrant re-classification. The axially viewed, jet-assisted glow discharge provides the highest detection power, but laterally viewing allows the potential for greater dynamic range, greater freedom from spectral interferences and a detection power comparable to the Grimm-type glow discharge. This makes lateral viewing of the jet-assisted plasma plume attractive for simultaneous multi-element applications.},
