Spatially resolved laser-induced fluorescence studies on a three-electrode direct current plasma

“…The SpectraJet HI three electrode direct current plasma (DCP) has attracted more interest than previous DCP designs [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]. This is mainly due to its success as an atomic emission source; detection limits have been reported [33,37] to be less than 1 ppm for many elements.…”
