Comparison of Microwave-Assisted Digestion Methods and Selection of Internal Standards for the Determination of Rh, Pd and Pt in Dust Samples by ICP-MS

Investigating the Influence of Non‐Spectral Matrix Effects in the Determination of Twenty‐Two Trace Elements in Rock Samples by ICP‐QMS

“…Niemelä et al . () argued that combinations of 101 Ru– 191 Ir, 101 Ru– 115 In and 191 Ir– 197 Au should be used for internal standardisation in the determination of 103 Rh, 105 Pd and 195 Pt, respectively, for correction of non‐spectral matrix effects during ICP‐MS measurements.…”

“…Chauvel et al (2011) used an internal standard solution containing five elements (Be, Ge, In, Tm and Bi) to correct for the sensitivity variation as a function of element mass for the determination of trace elements ranging from Li to U in basalt and sediment reference materials. Niemel€ a et al (2005) argued that combinations of 101 Ir, 101 Au should be used for internal standardisation in the determination of 103 Rh, 105 Pd and 195 Pt, respectively, for correction of non-spectral matrix effects during ICP-MS measurements.…”

Quantification of Noble Metals in Biological and Environmental Samples

“…Two steps of aqua regia treatment (aqua regia, HF/HClO 4 /aqua regia) was found effective for digestion of highly complex airborne particulate matter [54]. Quantitative recovery of Rh from dust samples can be problematic using wet chemical treatment [55]. Digestion with HF can result in higher amounts of the matrix elements being converted into soluble species and an increase in their interference with PGM detection.…”

A fast and accurate microwave-assisted digestion method for arsenic determination in complex mining residues by flame atomic absorption spectrometry

“…In studies involving the efficiency of the sample digestion with the aid of microwave radiation, different acid mixtures for sample dissolution are frequently compared [3,4,9]. However, the effect of the vessel type (i.e.…”
