Abstract: A method and apparatus for solution cathode glow discharge (SCGD) elemental analysis. A solution-catching collar, in the form of a weir, a wicking element, or combinations thereof between the outlet tip of the capillary tube and the base of a grounding electrode tip maintain a solution sample level proximate the plasma emission region.
