Multi-element analysis of soil and sediment by ICP-MS after a microwave assisted digestion method

Analysis of Environmental Samples Using Microwave-Assisted Acid Digestion and Inductively Coupled Plasma Mass Spectrometry: Maximizing Total Element Recoveries

“…As noted by others Falciani, Novaro, Marchesini, & Gucciardi (2000), microwave assisted acid digestion according to US EPA method 3051 does not provide a Table V Comparison of recoveries (%) obtained in Health Canada laboratory using HNO 3 alone versus mixture of HNO 3 /HCl, using 100 mg mass of CRM and 12 mL acid volume.

“…Therefore, the disadvantages of adding HCl to the HNO 3 acid digestion may outweigh the advantages, depending on the application and the ICP-MS equipment that is available. Because Cl ion is retained in the final sample matrix, interferences arise in the determination of 51 V (99.8% relative isotopic abundance), 52 Cr (83.8% relative isotopic abundance) and 75 As (100% relative isotopic abundance) during ICP-MS determination, due to the formation of the polyatomic ions 35 Cl 16 O, 35 Cl 16 O 1 H + or 40 Ar 12 C + and 40 Ar 35 Cl, respectively (Falciani et al, 2000). The ICP-MS instruments used in this study are equipped with dynamic reaction cell (Health Canada) and collision cell (Environment Canada) technologies, which assisted in minimizing the effect of the polyatomic ions of 51 V, 52 Cr, 56 Fe and 75 As.…”

Comparative study on open system digestion and microwave assisted digestion methods for metal determination in shrimp sludge compost

“…ICP-MS has emerged as a useful technique for trace analysis of soil owing to its multi elements capability, high detection power and low sample consumption [21]. The drawback of these techniques is that the solid sample required to be transformed into solution prior to the determination of the metal content [20].…”

Optimization of digestion parameters for analysing the total sulphur of mine tailings by inductively coupled plasma optical emission spectrometry

“…A method of digestion is developed for the analysis of the total sulphur of mine tailings by ICP, which provides better accuracy and precision. ICP has emerged as a useful technique in analysis of soil for its multi-element analysis capability, high detection power, and low sample consumption (Falcina et al 2000). However, sample preparation is still a major factor in uncertainties involved with the analytical results (Al-Harahsheha et al 2009).…”
