IODP Expedition 366 Gas safety report

This composite report returns data from two different gas chromatograph configurations (GC3 and NGA). Each row combines data from several measurements made on the same sample at the same time for a particular headspace or vacutainer sample. If data do not exist for a particular expedition, the column does not appear. Gas samples were measured by gas chromatography and either flame ionization detection (GC-FID) or thermal conductivity detection (GC-TCD). Reported analytes may include methane, ethane, ethene, propane, propene, n-butane, i-butane, n-pentane, i-pentane, n-hexane, i-hexane, n-heptane, i-heptane, nitrogen, oxygen, carbon monoxide, carbon dioxide, and hydrogen sulfide. When data are available, methane to (ethane + ethene) ratio is reported. To identify individual samples and tests, see each separate analysis (GC3, NGAFID, and/or NGATCD).本综合报告提供两种不同气相色谱配置（GC3与NGA）下获取的实验数据。每一行数据均整合了针对同一顶空样品或真空采血管样品，在同一时段内多次测量得到的结果。若某次特定采样任务未获取到对应数据，则该数据列不会出现在报告中。气体样品采用气相色谱法结合火焰离子化检测器（GC-FID）或热导检测器（GC-TCD）进行检测。本报告涵盖的分析物包括甲烷、乙烷、乙烯、丙烷、丙烯、正丁烷、异丁烷、正戊烷、异戊烷、正己烷、异己烷、正庚烷、异庚烷、氮气、氧气、一氧化碳、二氧化碳以及硫化氢。若数据可获取，则会报告甲烷与（乙烷+乙烯）的比值。如需识别单个样品与检测项目，请参阅各自独立的分析报告（GC3、NGAFID及/或NGATCD）。
