The Analysis of Ecstasy Tablets by Icp/ms and Icp/aes
In this study, tablets coming from different police seizures (in Switzerland) were analysed by ICP/MS and ICP/AES. Two methods of preparation were carried out in order to compare the influence of sample preparation. 25 elements were screened by ICP/AES whereas most of the periodic table could be screened by ICP/MS. Approximative detection limits were determined for most of the elements showing,...

متن کاملMetal in Ureilites: Siderophile Elements from La-icp-ms
Introduction: Bulk ureilites have near chondritic abundances of siderophile elements [1-7], showing no correlation with Fe contents (~5-16 wt.%) or mg (molar Mg/[Mg+Fe]). These observations are difficult to reconcile with any igneous model for their silicates [8]. We address this problem through detailed characterization of the metal phases in ureilites [9], and petrologic modelling [10]. Here ...
متن کاملLA-iMageS: a software for elemental distribution bioimaging using LA–ICP–MS data
The spatial distribution of chemical elements in different types of samples is an important field in several research areas such as biology, paleontology or biomedicine, among others. Elemental distribution imaging by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is an effective technique for qualitative and quantitative imaging due to its high spatial resolution and s...
متن کاملLaser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS): comparison of different internal standardization methods using laser-induced plasma (LIP) emission and LA-ICP-MS signals.
The source of signal variations that governs the analytical performance of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was investigated in this study. In order to specify the source of signal variations of LA-ICP-MS, laser-induced plasma (LIP) Fe emission, LA-ICP-MS Fe+ and LA-ICP-MS Ni+ signals were used as internal standards for the determination of trace elements ...
