IODP Expedition 361 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 (C1/C2 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）下的检测数据。每一行数据均整合了针对特定顶空样品或真空采血管样品，在同一时段内对同一样本进行多次测量所得的结果。若特定考察航次无对应检测数据，则该列不会在报告中出现。气体样品通过气相色谱法配合火焰离子化检测（GC-FID）或热导检测（GC-TCD）完成分析。本次报告涉及的分析物包括甲烷、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。若有对应数据，则会报告甲烷与（乙烷+乙烯）的比值（C1/C2比值）。如需识别单一样本及检测任务，请查阅各独立分析报告（GC3、NGAFID及/或NGATCD）。
