The samples were amino acid standard mix, blank, and Bennu. The sample extract was hot water extracted and derivatized with OPANAC. Each analysis produced two files, a .mzML chromatogram-mass spectrum and a .csv chromatogram-fluorescence file.

This dimension is the chromatographic retention time

This dimension is the mass-to-charge ratio measured by the mass spectrometer

This is a unitless measure of intensity of the mass peak

This describes the naming conventions of the analysis files, the standards used, which compound class is being analyzed, and the instrumental conditions for the analysis.

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