Quantification of lithium in molten chlorides by optical emission spectrometry using a novel molten-salt-electrode microplasma source

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…Sources. A molten-salt-electrode microplasma source was developed by Cai et al 57 The source effectively consisted of a metal T-piece with He plasma gas introduced through the side arm. A hollow stainless steel tube counter electrode was inserted into one end, axially in-line with a bre optic inserted into the opposite end.…”
