(1999)A new method is presented for the preparation of geological materials (water and rock) and their accurate analysis, by multiple collector magnetic sector ICP-MS, for the isotopic composition of lithium. Based on multiple ...
-
(2002)The NiS fire assay-Te coprecipitation separation procedure for inductively coupled plasma mass spectrometry (ICP-MS) analyses of platinum-group elements (PGE) in silicate rocks has been revisited with the aim of reducing ...
-
(2002)A novel flow-through method for cleaning and dissolving foraminiferal shells is presented. Using automated chromatographic equipment, the system chemically removes contaminant phases from the shells. The cleaned calcite ...
-
(2000)Three ordinary chondrites, Forest Vale (H4), Ste. Marguerite (H4) and Richardton (H5) have been studied with 182Hf-182W system (t1/2=9 million years [m.y.]) in order to provide constraints on the initial 182Hf/180Hf for ...
-
(2000)We investigated high-precision Pb isotope ratio analysis by multi-collector-inductively coupled plasma-mass spectrometry (MC-ICP-MS) using added thallium as an internal isotopic standard to correct for mass dependent ...
-
(2002)Pb isotope analyses using multicollector magnetic sector inductively coupled plasma mass spectrometers (ICP-MS) may potentially be corrected for mass bias, a major source of uncertainty, by assuming that the mass bias for ...
-
(1999)A method for analyzing low abundances of the platinum group elements (PGEs) and gold has been developed using cation exchange chromatography and ultrasonic nebulization inductively coupled plasma mass spectrometry (USN-ICP-MS). ...
-
(1999)New fire-assay and tellurium coprecipitation methods were developed for precise determination of Ru, Rh, Pd, Ir, Pt, and Au in geological samples by using ICP-MS. High recovery (>97%) of those elements was obtained by ...
-
(2000)We present a method for the rapid determination of Os isotopic compositions and platinum group element (PGE) concentrations using ICP-MS on the same sample split. The method makes use of transfer of volatile OsO4 by an Ar ...
-
(2000)A method is described that allows the separation of Re, Os, Pt, Pd, Ir and Ru for determination by isotope dilution via inductively coupled mass spectrometry (ICP-MS) at pg levels, from the same sample aliquot. Samples are ...
-
(2002)We have developed techniques by sector-field inductively coupled plasma mass spectrometry (ICP-MS) for measuring the isotopic composition and concentration of uranium and thorium, focusing on the rare isotopes, 230Th and ...
-
(2004)238U, 234U, and 230Th concentrations in samples of Baikal bottom sediments from the submerged Akademichesky Ridge were measured by ICP-MS, which is 100 times as fast as the traditional alpha spectrometry. These concentrations, ...

ГЕОХИМИЧЕСКИЕ ПОКАЗАТЕЛИ ГЕНЕЗИСА МЕСТОРОЖДЕНИЯ ЗОЛОТА ПАНИМБА В ЕНИСЕЙСКОМ КРЯЖЕ (СИБИРЬ, РОССИЯ) (2018)Рассмотрены особенности распределения редких и рассеянных элементов, а также благородных металлов в сульфидах и золоте месторождения Панимба (Енисейский кряж). На основании полученных данных предполагается комплексный ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Иркутский государственный университет», 2015)Обсуждаются новые результаты анализа содержаний металлов в нефтях Ярактинского, Западно-Аянского и Атовского месторождений Лено-Тунгусской нефтегазоносной провинции (Восточная Сибирь). Определения широкого спектра ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Московский государственный университет им. М. В. Ломоносова», 2017)Обсуждены вопросы, связанные с применением стандартных образцов для оценки и контроля качества результатов микроэлементного анализа горных пород методом ИСП-МС. Показано, что процессы, происходящие на разных стадиях ...
-
(Томский политехнический университет, 2019)Техногенез - глобальный процесс, оказывающий влияние на все геосферные оболочки Земли. Индикация воздействия промышленных объектов проводится с применением комплекса методов, включая биогеохимические исследования и мониторинг. ...
