Positive ion mode SFE-PTR mass spectrum of 0.2 μL (20 cells equivalent) of the methanol-extract of a cell

Positive ion mode SFE-PTR mass spectrum of 0.2 μL (20 cells equivalent) of the methanol extract of a cell.  Comma-separated arrays of m/z, intensity, and color code, where color code 15 suppose to be a sample-derived ion, and ten indicates a matched ion has been found in the non-HeLa cell control spectrum.
