Solid sampling electrothermal atomic absorption spectrometry for analysis of aluminium oxide powders

Determination of palladium, platinum and rhodium in used automobile catalysts and active pharmaceutical ingredients using high-resolution continuum source graphite furnace atomic absorption spectrometry and direct solid sample analysis

“…In this circumstance, it is important to consider the lifetime of the graphite parts. Typically, the analysis of relatively large amounts of samples with high Al 2 O 3 and/or high SiO 2 contents leads to the rapid deterioration of the graphite platforms owing to their interaction with graphite (C reduces these species) [33][34][35]. Therefore, and taking also into account the expected level of the analytes, selecting small sample aliquots (0.05 to 0.20 mg) seems preferable.…”

In situ Matrix Removal Studies and Determination of Trace Mn, Cr, and Cu in High Purity Tantalum Pentaoxide by Electrothermal Vaporization-Inductively Coupled Plasma Mass Spectrometry

“…Due to its unique physical and chemical characteristics, tantalum pentaoxide (Ta 2 O 5 ) has become an important material in the electrical, mechanical, steel, optical, aviation, and semiconductor industries (1,2). It should be pointed out that the growing application of advanced materials in high-tech fields enhances the demand for strictly controlled properties which are often directly correlated to the concentrations of trace impurities (3)(4)(5)(6). Therefore, a powerful, rapid, and reliable analytical method is required for the elemental characterization of impurities at trace and ultra-trace levels in Ta 2 O 5 .…”

Evaluation of solid sampling-electrothermal vaporization-inductively coupled plasma mass spectrometry and solid sampling-graphite furnace atomic absorption spectrometry for the direct determination of Cr in various materials using solution-based calibration approaches

“…When focusing on SS-GFAAS, it can be pointed out that while during the 1980s many calibration approaches were evaluated (including the use of certified reference materials, 9,10 home-made solid standards 11 and different standard addition approaches 12,13 ), in later years most of the recent papers have reported satisfactory results using external calibration with aqueous standards. 2,[14][15][16] This is owing to the generalized use of peak area integration as the measurement mode, the advances in instrumentation and the potential of chemical modification.…”
