Determination of traces of ruthenium by addition of cerium(IV) and atomic absorption spectrometry

High-efficiency photooxidation vapor generation of osmium for determination by inductively coupled plasma-optical emission spectrometry

“…Chemical vapor generation (CVG) is a widely used sample introduction method for trace element determination due to its high transport efficiency, effective matrix separation, simple operation and low-cost. [1][2][3][4][5][6][7][8][9] Several approaches are available in traditional CVG, including hydride generation (HG), 10,11 cold vapor generation, 12,13 alkylation, 14 oxidation, 15,16 halide generation, 17 and metal-carbonyl generation, 18 etc. These CVG techniques offer the advantage of high sensitivity, ease of implementation, and short analysis time.…”

GC-MS exploration of photochemically generated species of Os, W and Ru from reductive and oxidative media

“…Attempts to undertake GC-MS detection of RuO 4 possibly arising from PVG of Ru( iii ) in 5% v/v HNO 3 were unsuccessful. Although not completely surprising, as no signal was earlier detected by more sensitive ICP-MS sampling for this reaction medium, 28 chemical synthesis of RuO 4 for detection by flame AAS and ICP OES has earlier been reported, 39,40 attesting to its stability for this purpose.…”

Applications of chemical vapor generation in non-tetrahydroborate media to analytical atomic spectrometry

“…RuO 4 (g) can also be generated from a Ru(III) solution using Ce(IV) as an oxidizing agent. 301 Flame AAS was used for detection with this approach and the sensitivity was improved by a factor of 60. The authors attributed this to the increased rate of evaporation of Ru arising from the high volatility of RuO 4 .…”
