The effect of three different cone combinations on the performance laser ablation MC-ICP-MS (Neptune plus) for in situ Hf isotope analysis zircon were investigated. signal sensitivities Hf, Yb and Lu improved by a factor 1.4 2.5, respectively, with using X skimmer + standard sampler Jet sample compared to arrangement (H cone). However, when high-sensitivity cone, instrumental mass fractionation hafnium displayed large non-linear component that could not be corrected normal laws. magnitude...
The effects of adding nitrogen to the central gas flow (Ar + He) an Ar plasma in laser ablation inductively coupled mass spectrometry are presented. optimum rate was found be negatively correlated with N2 rate. addition 5–10 ml min−1nitrogen channel LA-ICP-MS increases sensitivity for most 65 investigated elements by a factor 2–3. degree enhancement depends, some extent, on 1st ionization energy. Another important advantage mixed is that oxide ratios (ThO+/Th+) significantly reduced (one...

The low‐Sr content (generally < 100 μg g −1 ) in clinopyroxene from peridotite makes accurate Sr isotopic determination by LA ‐ MC ICP MS a challenge. effects of adding N 2 to the sample gas and using guard electrode ( GE on instrumental sensitivity for were investigated. Results revealed no significant enhancement . Although led two‐fold enhancement, it significantly increased yield polyatomic ion interferences Ca‐related ions TiAr + isotopes.

Complete sample digestion is a prerequisite for achieving reproducible and accurate analytical results geological samples. Open-vessel acid digestions successfully dissolve mafic samples, but this method cannot achieve complete dissolution of felsic because the presence refractory minerals such as zircon. In study, an efficient simplified technique using solid compound NH(4)HF(2) in screw-top vial has been developed multielement analysis different types rock higher boiling point (239.5 °C)...
With a 5% NaCl rinse solution, the Li background can be effectively reduced by factor of 15 to 70.
Abstract Carbon in rocks and its rate of exchange with the exosphere is least understood part carbon cycle. The amount carbonate subducted as sediments ocean crust poorly known, but essential to mass balance We describe carbonatite melt pockets mantle peridotite xenoliths from Dalihu (northern China), which provide firsthand evidence for recycling within subduction system. These retain low trace element contents δ 18 O SMOW = 21.1 ± 0.3 argillaceous sediments, representing wholesale melting...

Complete dissolution is essential to obtain accurate analytical results for geological samples. Felsic rocks are known be very difficult dissolve because of the presence refractory minerals such as zircon. In this study, we undertook a systematic evaluation effect HF/HNO3 ratio, digestion time, temperature, digested test portion mass and insoluble fluorides on felsic rock GSP-2 using high-pressure HF digestion. Digestion in mixtures HNO3 acids commonly used method However, our clearly...
