Abstract
UV lasers can be used to produce microplasmas efficiently in gaseous flows.1,2 The detection of species in the effluent gas of gas chromatography (GC) is one application for the use of such laser-produced microplasmas. For this application to be viable, microplasma formation must occur only when a hydrocarbon analyte is present in the He carrier gas flow and not in the presence of the carrier gas flow alone. Since one of the characteristics of microplasma formation is the emission of electromagnetic radiation, the laser-produced microplasmas are suitable for detection by photometric means.
