Improved method and scavenger gas for the analysis of oxygen-containing components using atomic emission spectrometry. |
摘要 |
<p>The oxygen-selectivity of an atomic emission detection system is enhanced by introducing a carbon-containing, preferably non-oxygenated, gas as a portion of the reagent gas. In preferred embodiments, the reagent gas is nitrogen and/or hydrogen and up to about 50 volume percent of a C1-C4 hydrocarbon gas, e.g. propane or n-butane.</p> |
