CO2 sequestration using brine impacted fly fish
… carbonation leachates were characterized using inductively coupled mass spectrometry and ion chromatography. Total acid digestion was carried out to evaluate the differences in the total elemental content in both the fresh ash and the carbonated solid residues. The results suggested that South …

Proterozoic history of the Idaho Springs-Ralston shear zone: evidence for a widespread ca. 1.4 Ga orogenic event in central Colorado, The
… NW-dipping F3 fold. U-Pb laser ablation inductively coupled mass spectrometry monazite dates revealed ~1.68 Ga and ~1.43 Ga events, both within and adjacent to the IRSZ. Relationships between microstructures and monazite grains suggest F1 folds formed at ~1.68 Ga and F2 and F3 folding and …

Implementing a new method to measure δ³⁴SSO₄ in ice cores to assess sulfate sources in West Antarctica
… measure δ³⁴SSO₄ in ice cores via multicollector inductively coupled mass spectrometry (MC-ICP-MS) at the University of Cambridge. This technique requires < 30 nmol of sulfur compared to the ~1 µmol previously required for analysis with gas source mass spectrometry (GS-MS). Using this method, I …

Mineralogy and geochemistry of geophagic materials from Mashau Village in Limpopo Province, South Africa
… were determined using x-ray fluorescence (XRF) spectrometry and laser ablation inductively coupled mass spectrometry (LA-ICP-MS), respectively. Furthermore, provenance of the geophagic materials was determined using data obtained from mineralogical and geochemical analysis. Inferred health …

Characterization of volcanic ash from 2010 Mt Merapi, Indonesia eruption by neutron activation analysis and leaching analysis
… system. The leachate was analyzed by an inductively coupled plasma mass spectrometer (ICP-MS), and the results were compared to the original material present in the ash. Several potentially toxic metals and metalloids leached out of the system at relatively high rates. For example, 2.7% …

Characterization of Arsenic by High Performance Liquid Chromatography and Inductively Coupled Plasma Mass Spectrometry of Algal Extracts and Water in Evaporation Ponds
Arsenic is a toxic element and its effects on humans, animals and other organisms are well documented. A method to accurately determine the concentration as well as the speciation of arsenic in highly complex evaporation pond water and algae will be discussed. Interestingly, microorganisms are …

An integrated approach of determining shale gas potentiality of carbonaceous shale of the Permian Tuli Basin, Limpopo Province of South Africa
… X-ray fluorescence (XRF) and Laser Ablation Inductively Coupled Mass Spectrometry (LA-ICP-MS) respectively. In addition to the mineralogical characterisation using X-ray diffraction (XRD), the functional groups of organic compounds in studied samples are identified using Fourier Transform …
