Negative ion mode SFE-PTR mass spectrum of a cell on the frit

Negative ion mode SFE-PTR mass spectrum of a cell on the frit.  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.

负离子模式下，于滤网处的细胞 SFE-PTR 质谱图。m/z、强度和颜色代码以逗号分隔的数组呈现，其中颜色代码 15 意指由样本衍生出的离子，而数字十表示在非 HeLa 细胞对照谱图中找到了匹配的离子。
