Influence of sample treatment after bomb digestion on determination of trace elements in rock samples by ICP-MS

An Improved Procedure for the Determination of Trace Elements in Silicate Rocks Using NH4HF2 Digestion

“…2012b, Okina et al . 2018). In this study, a series of experiments was designed to optimise the HClO 4 evaporation process (Table 2).…”

“…However, the disadvantages of evaporation with perchloric acid include possible losses of some elements due to hydrolysis (Ta, Nb, W, Sn, Mo; Okina et al . 2018), and the introduction of chloride interferences in ICP‐MS (Hu and Qi 2014). Many improvements have been proposed to avoid or eliminate fluoride precipitation during the sample digestion steps.…”

Determination of major elements in igneous rocks using microwave plasma atomic emission spectrometry (MP-AES)

“…The most widely used for trace element analysis are inductively coupled plasma mass spectrometry (ICP-MS) and instrumental neutral activation analysis (INAA). Since the introduction of commercial ICP-MS spectrometers, and due to its high sensitivity, multielement capability, selectivity, and precision it has been chosen as the gold technique for the determination of trace and ultratrace elements in rock samples [2] , [3] , [4] , [5] , [6] , [7] . Despite the increased use of trace elements in geochemistry, major element determination continues to be essential and the most used techniques for its determinations are X-ray fluorescence (XRF) and inductively coupled plasma optical emission spectrometry (ICP OES) [8] , [9] , [10] , [11] .…”
