Unravelling the timing and rate of subduction-zone metamorphism and H2O release requires linking time to the compositional changes of petrogenetic indicator minerals in blueschists and eclogites. Garnet is a key mineral in this regard, as it
Long-term, high resolution measurements of dual clumped isotopes in carbonatesusing the Perspective IS The Nu Perspective IS stable isotope ratio mass spectrometer is designed to measure isotopic clumping in gas
ABSTRACT The western North American Great Basin’s Carlin-type deposits represent the largest accumulation of gold in the Northern Hemisphere. The controversy over their origins echoes the debate between Neptunists and
Abstract Bár általánosan elismert, hogy az La-ICP-MS a leggyorsabb technika elemtérképek készítésére. A köztudományú vélekedés szerint ebben az esetben romlik a kimutatási határ a kép készítése során. A modern lézeres ablációs
Abstract Post-collisional highly potassic magmatism in large orogenic belts has been taken as evidence for recycling of continent-derived K-rich sediments within the orogenic lithospheric mantle. Potassium isotopes may provide important
Abstract The Fe isotopic composition of the riverine suspended particulate matter (SPM) in the Mun River was found to improve the knowledge of the Fe isotope behaviors in the surface
Abstract Calcium isotope meaurements apply to problems spanning the ‘cosmos to benthos.’ Fractionation, source mixing, radioactive decay, and nucleosynthetic processes cause variations in Ca isotope ratios, which can be measured
Abstract Mass-dependent K isotopic fractionations can be used to trace cosmochemical, geological, and biological processes such as evaporation/condensation, core formation, magmatic processes, weathering, and cellular metabolism. However, the application of
Abstract Malignant mesothelioma is an aggressive cancer associated with exposure to asbestos. Diagnosis of mesothelioma and other related lung diseases remains elusive due to difficulties surrounding identification and quantification of
Abstract With growing applications of TiO2 nanoparticles (NPs) in outdoor surface coatings, notably in paints and stains, their release into the environment is inevitable. While NP release has potential ecotoxicological
Abstract The interaction of incident laser radiation and sample substrate is complex and difficult to predict. Natural zircons are often both structurally and chemically heterogeneous in 3-dimensional space. Encountering growth-related,
Abstract Trace metal micronutrients play key roles in photosynthesis by oceanic phytoplankton. Though they are required in much smaller amounts than the major nutrients (P, N, Si), their bioavailable forms
Abstract The Mansehra granite in the NW Himalaya is a typical Lesser Himalayan granite. We present here new whole-rock geochemistry, Rb–Sr and Sm–Nd isotope data, together with zircon U–Pb ages
Abstract Inductively coupled plasma mass spectrometry (ICP-MS) is proving to be a useful tool for characterization and quantification of metallic nanoparticles. However, the short (200–400 μs) transient signals generated by
Abstract Precise measurement of 234U/238U and 235U/238U isotope ratios was performed using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) in this study. The 234U ions were measured using a Daly
Abstract Single particle ICP-MS (spICP-MS) is a useful tool for characterizing and quantifying suspensions of metallic nanoparticles, but there are currently limitations on the minimum size of nanoparticles that can
Abstract Nanoparticle (NP) emissions to the environment are increasing as a result of anthropogenic activities, prompting concerns for ecosystems and human health. In order to evaluate the risk of NPs,
Abstract Iron (Fe) is an essential element for bio-physiological functioning terrestrial organisms, in particular of aquatic organisms. It is therefore crucial to understand the aquatic iron cycle and geochemical characteristics,
Az MC-ICP-MS működését tekintve ötvözni a minta plazma álltali ionizációját és a megneses tér szeparáló képességét. De mitől is egyedi egy mc-icp-ms? A titok nem más mint azon mérnöki apróságok
Sapphire a mai kor kihívásaira nyujt tökéletes megoldást. Kutatásban nélkülözhetetlen precizitás és lehetőség a stabil izotóp és elemanalítika területén. Dr. Ye Zhao előadása kitűnő betekintést nyújt a készülék adta lehetőségekbe.
A NASA vezető tudósainak egyik kiemelt kutatási területe a naprendszer eredetének és titkainak feltárása. 2019 nyarától a Nu Instruments Sapphire 1700 MS tömegspektrométerrel rendelkeznek a NASA kutatói. A kifejezetten úttörő kutatásokra szabott tömegspektrométer a világ legnagyobb kereskedelmi forgalomban kapható Multi-Collector ICP-MS készüléke.
