At a particular density and temperature , some fraction of helium will be neutral , some fraction will be singly ionized , and some fraction will be doubly ionized . Web1 feb. 2024 · Nitrogen can be an inexpensive alternative to helium used by direct analysis in real time (DART), especially in consideration of the looming helium shortage. Therefore, the ionization mechanism of positive-ion N2 DART has been systematically investigated. Our experiments suggest that a range of metastable nitrogen species with a variety of … blender pin empty to armature
