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

Negative 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.负离子模式下的 SFE-PTR 质谱数据，源自 0.2 微升（相当于 20 个细胞）的甲醇提取物细胞样本。该数据集以逗号分隔的数组形式呈现，包括质量/电荷比（m/z）、强度和颜色代码，其中颜色代码 15 代表由样本衍生出的离子，而数字 10 则表明在非 HeLa 细胞对照光谱中已找到匹配的离子。
