SSHCZO -- Stable Isotopes, Stream Water Chemistry -- Shale Hills -- (2008-2011)

Quality assured stream water stable isotope data has been prepared using Liquid Water Isotope Analyzer. Samples were analyzed following IAEA Standard Operating Procedure. Daily stream water samples were collected using ISCO Sampler at the stream outlet. Samples were plotted compared to the Local Meteoric Water Line (LMWL). Water samples were analyzed on DT-100 Liquid-Water Isotope Analyzer: http://www.lgrinc.com/analyzers/overview.php?prodid=16 IAEA Standard Operating Procedure was followed with in-house standards: http://www-naweb.iaea.org/napc/ih/documents/other/laser_procedure_rev12.PDF Deuterium (2H) and Oxygen-18 (18O) isotope values were calculated to within 1‰ and 0.2‰ respectively.

为确保水质流水的稳定同位素数据质量，已采用液态水同位素分析仪进行制备。样品分析遵循国际原子能机构（IAEA）的标准操作程序。每日流水样品采用ISCO采样器在出水口采集。样品与当地降水线（LMWL）进行对比分析。水样在DT-100液态水同位素分析仪上进行检测：[DT-100液态水同位素分析仪](http://www.lgrinc.com/analyzers/overview.php?prodid=16)。分析过程中遵循了IAEA标准操作程序及内部标准：[IAEA标准操作程序](http://www-naweb.iaea.org/napc/ih/documents/other/laser_procedure_rev12.PDF)。计算得到氘（2H）和氧-18（18O）同位素比值，其精确度分别达到±1‰和±0.2‰。
