Analysis of dissolved metals in acid rock drainage (ARD) with an Agilent 4100 MP AES instrument that combines a nitrogen micro plasma with atomic emission detection (MP AES) was compared with an ICP-MS. Sample preparation consisted only of filtration, acidification (HNO3 1%) and addition of internal standard elements after appropriate dilution. In these complex matrices the systems gave identic...

In order to miniaturize a high-density, inductively coupled magnetized plasma or helicon plasma to be applied to, e.g., an industrial application and an electric propulsion field, small helicon device has been developed. The specifications of this device along with the experimental results are described. We have succeeded in generating high-density (~10(19) m(-3)) plasmas using quartz tubes wit...
High pressure inductively coupled plasma (ICP) sources are used in numerous applications, in particular for the testing of thermal protection materials used to protect space (re-)entry vehicles. The planetary gas is injected in a swirling, annular way into a heat-resistant quartz tube, surrounded by an inductor. A radio-frequency electric current runs through the inductor and induces a secondar...
Inductively Coupled Plasmas (ICPs) can be maintained over a wide range of driving frequencies, from 50 Hz to GHz. We have investigated the specifics of ICP operation at different frequencies which address: a) nonlinear plasma dynamics due to the disparity of time scales for ion transport and electron energy relaxation, b) the absence of time-varying magnetic field in plasma for certain ICP conf...
Iron-60 (t1/2= 2.62Myr) is a short-lived nuclide that can help constrain the astrophysical context of Solar System formation and date early Solar System events. A high abundance of Fe(Fe/Fe ≈ 4 × 10) was reported by in situ techniques in some chondrules from the LL3.00 Semarkona meteorite, which was taken as evidence that a supernova exploded in the vicinity of the birthplace of the Sun. Howeve...
Fast-(semi)quantitative elemental mapping using state-of-the-art laser ablation-inductively coupled plasma-time of flight-mass spectrometry (LA-ICP-TOF-MS) was applied to a set chondritic meteorite samples.
