We also show that mass-time-intensity drift curve is smooth as recognized previously, for which the correction can be readily done by analyzing a qualitycontrol (QC) solution and using off-line Excel VBA procedure without internal standards. With these methods, we can produce data in reasonable agreement with recommended values of international rock reference standards with a relative error of < 8% and precision generally better than 5%. Importantly, compared to the widely used analytical practice, we can effectively save > 60% of time (e.g., < 24 hours vs. > 60 hours).

Petrogenesis of ODP Hole 735B (Leg 176) Oceanic Plagiogranite: Partial Melting of Gabbros or Advanced Extent of Fractional Crystallization?

“…All suspicious surface contaminants such as pen marks, saw marks, and sticker residues were thoroughly removed. Analytical accuracy is better than 8%, with many elements agreeing to within 5% of the reference values, except for Ni, Co, Cu, and Ce ranging between 8% and 10% and Li, Be, Cr, and Pb ranging between 10% and 19% (see Chen et al, 2017, for analytical details). Bulk-rock major ; Ol in the troctolite along the contact were altered to talc.…”

The Lithospheric Thickness Control on the Compositional Variation of Continental Intraplate Basalts: A Demonstration Using the Cenozoic Basalts and Clinopyroxene Megacrysts From Eastern China

“…Detailed erupting ages of these basalts are compiled in Table S2. Basalts from northeast China with rare cpx megacrysts (e.g., Chen et al, 2017; Zhang et al, 1995) and basalts from the Leizhou Peninsula and Hainan Island (Figure 1) showing extreme mantle source heterogeneity possibly influenced by the Hainan mantle plume (Flower et al, 1992; Sun et al, 2019; Tu et al, 1991; X. Wang, Li, et al, 2011) are not included here.…”

Determination of Trace Elements in Bauxite Using Laser Ablation‐Inductively Coupled Plasma‐Mass Spectrometry on Lithium Borate Glass Beads

“…, Cotta and Enzweiler , Chen et al . ). Hence, special optimisation of the acid digestion method is recommended to accurately determine trace element contents of bauxite samples by ICP‐MS (Zhang et al .…”

“…Mixed acid attack may result in incomplete recoveries of analytes if resistant minerals are present, or as insoluble AlF 3 precipitates form that could incorporate significant amounts of trace elements (Yu et al 2003, Cotta and Enzweiler 2011, Chen et al 2017. Hence, special optimisation of the acid digestion method is recommended to accurately determine trace element contents of bauxite samples by ICP-MS (Zhang et al 2016).…”

“…LA-ICP-MS also offers several major advantages compared with more conventional analytical methods for the analysis of solid fusion beads such as XRF, including the multi-element determination capability coupled with high detection power. On the other hand, accuracy and precision in LA-ICP-MS can be limited by elemental fractionation at or close to the site of ablation, incomplete ionisation of the particles in the plasma, relatively poor stability of the plasma source, spectroscopic interferences, difficulties in correcting for ablation yield and the lack of suitable matrix-matched reference materials (e.g., Longerich et al 1996, Mason and Kraan 2002, Yu et al 2003, Jochum et al 2007, Regnery et al 2009, Miliszkiewicz et al 2015, Shazzo and Karpov 2016, Zhang et al 2016, Chen et al 2017.…”
