Description

The NanoSIMS 50L at NASA JSC was used to analyze concurrently the isotopes 12C, 13C, 12C14N, 12C15N, 28Si, 30Si, and 32S in sample OREX-501018-100 through raster ion imaging. On the sample, seven 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 and C-rich presolar grains. Kerogen (KG17) was measured as a C and N isotopic standard, and graphite was measured as a C isotopic standard for presolar SiC and graphite grains.
