Quantification of stable isotope tracers has revealed the dynamic state of living tissues. A new form of imaging mass spectrometry quantifies isotope ratios in domains much smaller than a cubic micron, enabling measurement of cell turnover and metabo

Quantitative information on the ecophysiology of individual microorganisms is generally limited because it is difficult to assign specific metabolic activities to identified single cells. Here, we develop and apply a method, Halogen In Situ Hybridiza

Sorption of actinides, particularly plutonium, onto submicrometer-sized colloids increases their mobility, but these plutonium colloids are difficult to detect in the far-field. We identified actinides on colloids in the groundwater from the Mayak Pr

NanoSIMS 50: Recent Results and Intrumental Development in Submicron Isotopic and Elemental Analysis

Autor: Francois Hillion, Francois Horreard, Cecile Fournier

Publikováno v: Microscopy and Microanalysis. 7:890-891

Secondary Ion Mass Spectrometry (SIMS) has unique features that makes this technique a very attractive candidate for sub-micron analysis: high elemental sensitivity (ppm or better) if reactive primary ions are used ; isotopic analysis capability ; po
