“…69 The idea, to use a high and directed gas flow in a GD source to improve the analytical figures of merit by a gas jet assisted sputtering was applied first by Gough who used the GD as a sputter source for atomic absorption measurements. 70,71 By application of a gas jet the atomic vapour density could be enhanced so that the sensitivity of atomic absorption spectroscopy could be improved by about one order of magnitude. In such a device, several processes are contributing independently.…”

“…Such a device had already been applied by Gough, who used the GD as a sputter source to produce an atom reservoir for atomic absorption measurements, which was later used in a commercial instrument (Atom Source, Leemann Labs, Fishkill, New York). 34,35 The atomic vapour density could be enhanced by application of a gas jet so that the sensitivity of atomic absorption spectroscopy could be improved by one order of magnitude. In such a device, several processes contribute independently.…”

“…The use of a fast flowing discharge gas was first investigated for GD optical analysers. 4 It was found that gas in the form of a jet directed at the sample helped to improve the erosion characteristics of flat plate samples and increased the analyte concentration in the plasma, hence improving the sensitivity of the technique. 5 Kim and Piepmeier 6 adapted a commercially available flowing optical source as an ion source replacement for the inductively coupled plasma (ICP) source of a 'PQII' mass spectrometer.…”
