Nafion-coated bismuth film electrodes (NCBFEs) and Nafion-coated mercury film electrodes (NCMFEs) were used to electrochemically preconcentrate metal analytes for subsequent analysis by inductively coupled plasma-mass spectrometry (ICP-MS). Either type of electrodes is part of a thin-layer electrochemical flow cell that is positioned upstream of a microconcentric nebulizer for the ICP-MS. Perfo...

Understanding post-depositional processes altering the layer sequence in ice cores is especially needed to avoid misinterpretation of oldest and most highly thinned layers. The record soluble insoluble impurities represents an important part paleoclimate proxies but known be affected through interaction with matrix, diffusion, chemical reactions. Laser ablation inductively coupled plasma mass s...

We present a comparison of two different techniques: Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and wavelength-dispersive X-Ray Spectroscopy by electron probe microanalyzer (EPMA) for obtaining Mg/Ca ratios in individual foraminifera shells. The goal is to assess the use EPMA as an alternative technique analyses single foraminiferal calcite Foraminifera obtained fro...
