NanoSIMS H isotopic analysis of fines in sample OREX-501018-100

The NanoSIMS 50L at NASA JSC was used to analyze concurrently the H, D, 13C, and 18O in sample OREX-501018-100 through raster ion imaging. For some regions, 16O was also collected. On the sample, isotope maps were collected for 20 micrometer fields of view. These 20-micron regions were analyzed sequentially during chained analyses. The data were collected with the goal of identifying isotopically anomalous organic matter. Kerogen (KG17) was measured as a H isotopic standard.
