NanoSIMS C and O isotopic analysis of fines in sample OREX-501018-100
Ann Nguyen. 2024
The NanoSIMS 50L at NASA JSC was used to analyze concurrently the 12C, 13C, 16O, 17O, 18O, 28Si, and 24Mg16O in sample OREX-501018-100 through raster ion imaging. 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 presolar grains. A cluster of forsterite grains were also targeted for O isotopic analysis. San Carlos olivine (16O, 17O, 18O) and graphite (12C, 13C) were measured as isotopic standards.

NanoSIMS H isotopic analysis of fines in sample OREX-501018-100
Ann Nguyen. 2024
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.

NanoSIMS C, N, and Si isotopic analysis of fines in sample OREX-501018-100
Ann Nguyen. 2024
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.

Chemical composition of Bennu samples
Kees Welten. 2023
This dataset shows the chemical composition of the Orgueil CI chondrite and five Bennu particles, named OREX-803048-0, OREX-803049-0, OREX-803050-0, OREX-803051-0 and OREX-803052-0, from aggregate sample OREX-803014-0 that were dissolved for cosmogenic radionuclide analysis. A small aliquot (~7%) of each of the dissolved samples was taken for chemical analysis by ICP-OES. These splits are named OREX-803048-100 thru OREX-803052-100.
