Micrometer-scale ion images of the cross-section of SaU 290 (CH3 chondrite), recorded by the NanoSIMS 50L at Academia Sinica. A ~10 pA Cs+ primary beam with a nominal spot size of 100 nm and rastered over 20 × 20 µm, to image the sample surface simultaneously in several ion species. A total of 160 (10 × 16 rows) individual images were recorded, and these were combined to create maps in a) 16O- and b) 18O-, as well as c) secondary electrons.

The cross-section of Sayh al Uhaymir (SaU) 290, a CH3 chondrite, observed by the NanoSIMS in a) secondary electrons, b) <sup>16</sup>O<sup>−</sup>, c) <sup>12</sup>C<sub>2</sub><sup>−</sup> and d) <sup>12</sup>C<sup>14</sup>N<sup>−</sup>. Each square grid represents a single NanoSIMS image, capturing a surface area of 20 × 20 μm<sup>2</sup>. By recording and stitching a large number of these single images, the maps (a) - (d) were created to analyse the microscale surface morphology and chemical distribution of SaU 290.

The NanoSIMS Laboratory was established by a cooperative effort between Institute of Astronomy and Astrophysics and Institute of Earth Science of Academia Sinica. The laboratory is primarily designed to probe the early Solar System by analysing extraterrestrial and terrestrial samples with CAMECA's NanoSIMS 50L. Located in Interdisciplinary Research Building for Science and Technology, Academia Sinica, it is the only NanoSIMS in Taiwan and was installed as the 33rd NanoSIMS in the world in November 2013. The laboratory is involved in numerous interdisciplinary collaborations with both domestic and international research groups. Current research activities cover, nuclear astrophysics, astrobiology, geochemistry, marine biochemistry and plant biology.
