The gaseous state includes free atoms, molecules and radicals. This quantity is measured in a defined part of the flame, usually the observation space. The fraction volatilized varies inversely with the size of the desolvated particles. Since \\(\\chi _{\\rm{v}}\\) varies markedly with the height in the flame, its observed value represents an average.","contexts":[],"links":[{"term":"substance fraction","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/S06075"}],"sources":["Orange Book, 2nd ed., p. 168 (https:\/\/media.iupac.org\/publications\/analytical_compendium\/)","PAC, 1986, 58, 1737.
