The analytical capabilities of a nitrogen-sustained high-power microwave inductively coupled atmospheric-pressure plasma mass spectrometer (N2 MICAP-MS) were investigated using solution nebulization with and without aerosol desolvation. The...
Platinum-group elements and gold in silver coinage and the issue of salt cementation [0.03%]
银币中的铂系元素和金及其与盐胶结的关系问题

Francis Albarède
It has been proposed that gold purification by cementation could account for the low gold content of ancient Greek coinage from Attica and the Cyclades. In order to place new constraints on this suggestion, the concentrations of platinum-gr...
Interference-free electron probe micro-analysis of bromine in halogen-bearing minerals and glasses: high-resolution measurements and quantitative elemental mapping [0.03%]
卤素矿物和玻璃中溴的无干扰电子探针微区分析：高分辨测量及定量元素mapping
Johannes Hammerli,Scott Boroughs
Johannes Hammerli
Previous attempts to measure Br in minerals and glasses via electron probe micro-analyzers (EPMA) required interference corrections via calibration curves in order to account for Al X-ray overlap with the Br Lβ X-ray signal. We present a n...
High spatial resolution (10-50 μm) analysis of Sr isotopes in rock-forming apatite by LA-MC-ICP-MS [0.03%]
激光微区多接收器电感耦合等离子体质谱法测定岩浆apatite中锶同位素的空间分布（英文）
Anda Buzenchi,Hugo Moreira,Olivier Bruguier et al.
Anda Buzenchi et al.
In situ Sr isotopes analysis of apatite by LA-(MC)-ICP-MS is challenged by the difficulty to monitor and correct isobaric interferences from atomic and polyatomic ions. We present a new routine procedure for analysing rock-forming apatites ...
Reduction of surface charging effects in laser ablation ionisation mass spectrometry through gold coating [0.03%]
通过金涂层减少激光烧蚀电离质谱中的表面充电效应

Salome Gruchola et al.
In femtosecond Laser Ablation Ionisation Mass Spectrometry (fs-LIMS) short laser pulses are used to ablate, atomise, and ionise solid sample material shot-by-shot. When ablating non-conductive samples electric charging of the surface can oc...
