LC-MS and LC-Fluorescence analysis of Bennu, Murchison, and Fused Silica samples.  Extraction performed via hot water, followed by AccQ-Tag derivatization.  Each analysis produced two files: .mzml (chromatogram-mass spectrum)  and .cdf (chromatogram-fluorescence).


This describes the naming conventions, standards used, compound class, and instrumental conditions.

This describes the preparation of the sample before analysis (e.g., extraction, derivatization).
