LINK<\/strong><\/a><\/p>\n\n\n\n“Here, we discuss the merits of non\u2010destructive UV laser\u2010induced fluorescence spectroscopy (LIF) as a flight or laboratory instrument to analyze organic and mineral material in samples on or returned from carbon\u2010rich asteroids such as (101955) Bennu by NASA\u2019s OSIRIS\u2010REx mission. LIF is a unique instrument that is non\u2010destructive while acquiring data, and allows for no sample preparation, crushing, or cutting. This method provides spectral data indicative of specific minerals and organics in less time than Raman spectroscopy, and can be set up to produce 2\u2010D raster images of areas of interest. Furthermore, if an LIF system is set up with a gated CCD camera, time\u2010resolved fluorescence spectroscopy can be performed, providing a unique identification tool for organic and mineral contents using fluorescence decay over several nanoseconds. This technique was used to analyze millimeter\u2010sized chondrules and calcium\u2010aluminum\u2010rich inclusions on four carbonaceous chondrite samples provided by the Royal Ontario Museum: Murchison (CM2), Allende (CV3), NWA 11554 (CV3), and NWA 12796 (CK3). The LIF 2\u2010D maps, point spectra, and time\u2010resolved fluorescence data and mineral identifications using LIF were compared to that of well\u2010known techniques such as Raman spectroscopy and SEM\/EDS.”<\/p>\n","protected":false},"excerpt":{"rendered":"
