Direct measurement of Fe isotope compositions in iron-dominate minerals without column chromatography using MC-ICP-MS

This study presents a practical method for high-precision Fe isotope determination without column chromatography purification for iron-dominated mineral samples using multi-collector inductively coupled plasma-mass spectrometry (MC-ICP-MS). A series of comparable...

Direct analysis of cotton swipes for plutonium isotope determination by microextraction-ICP-MS

This study demonstrates a method for determining the isotopic composition of low-level (sub-pg) plutonium (Pu) directly from a cotton swipe. Environmental sample (ES) swipes are routinely employed as a tool...

TC1725 - A Proposed Chalcopyrite Reference Material for LA-MC-ICP-MS Sulfur Isotope Determination

Sulfur isotope is an important geochemical tracer in diverse fields of geosciences. Controlling the accuracy and precision of microanalysis of sulfur isotope requires well-characterized reference materials with matrices similar to...
