Scope

本试验方法主要描述了用硫化学发光检测气相色谱仪测定燃料电池车（FCV）用氢燃料中硫化氢、羰基硫、甲硫醇和二硫化碳（表1）的方法。根据对500毫升氢样品的分析，报告限值为0.02 ppbv（每摩尔体积为纳米摩尔）。本方法中所述的程序旨在满足SAE TIR J2719和加州法规CFR标题4第9部分第6章第8条第4180节中包含的硫污染物测定要求？公元4181年。本试验方法可推广到氢燃料中通过色谱柱洗脱的其他硫种。本试验方法可进行修改，以在不进行色谱分离的情况下分析所有含硫化合物；从而提供不进行形态分析的总硫估算（附录X1）。如果需要在氢燃料中分析任何新的硫化合物，则在对其方法检测限研究之后，校准或峰值硫标准必须包括这些新化合物。此外，在含有新添加和现有硫目标化合物的校准标准品的色谱分析中，不允许进行共洗脱。如有必要，可修改色谱条件以达到此目的。虽然主要用于测定燃料电池或内燃机驱动车辆燃料氢中的硫，但如果满足数据质量目标，本试验方法也可用于测量其他气体燃料和气体基质中的硫化合物。以国际单位制表示的数值是标准值。以英寸磅为单位的数值仅供参考。本标准中提及的商品名称不构成认可或使用建议。可使用其他设备制造商或设备型号。替代探测器？本试验方法主要用于硫化学发光检测器，但也可使用其他检测器，前提是它们可以检测氢中0.02 ppbv的硫化氢羰基硫甲硫醇和二硫化碳，并满足预期用途的数据质量目标。本标准并不旨在解决与其使用相关的所有安全问题。本标准的使用者有责任在使用前建立适当的安全和健康实践，并确定法规限制的适用性。有关液氮的安全问题，请参阅液氮供应商提供的材料安全数据表（MSDS）。 This test method describes a procedure primarily for the determination of hydrogen sulfide carbonyl sulfide methyl mercaptan and carbon disulfide (Table 1) in hydrogen fuels for fuel cell vehicles (FCV) by gas chromatograph with sulfur chemiluminescence detection. The reporting limit is 0.02 ppbv (nanomole per mole as volume) based upon the analysis of a 500 mL hydrogen sample. The procedures described in this method were designed to satisfy sulfur contaminant determination requirements contained in SAE TIR J2719 and the California Code of Regulations CFR Title 4 Division 9 Chapter 6 Article 8 Sections 4180?C 4181. This test method can be extended to other sulfur species in hydrogen fuel that are eluted through a chromatographic column. This test method can be modified to analyze all sulfur compounds present without chromatographic separation; thus providing a total sulfur estimation without speciation (Appendix X1). If any new sulfur compounds need to be analyzed in hydrogen fuel the calibration or spiking sulfur standards must include these new compounds after their method detection limit study. In addition no co-elution is allowed in the chromatographic analysis of the calibration standard containing both the newly added and the existing sulfur target compounds. If necessary the chromatographic conditions may be modified to achieve this goal. Although primarily intended for determining sulfur in hydrogen used as a fuel for fuel cell or internal combustion engine powered vehicles this test method can also be used to measure sulfur compounds in other gaseous fuels and gaseous matrices provided data quality objectives are satisfied. The values stated in SI units are standard. The values stated in inch-pound units are for information only. Mention of trade names in this standard does not constitute endorsement or recommendation for use. Other manufacturers of equipment or equipment models can be used. Alternative Detectors?This test method is written primarily for the use of sulfur chemiluminescent detectors but other detectors can be used provided they can detect hydrogen sulfide carbonyl sulfide methyl mercaptan and carbon disulfide at 0.02 ppbv in hydrogen and meet data quality objectives for the intended use. This standard does not purport to address all of the safety concerns if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For safety issues related to liquid nitrogen refer to material safety data sheet (MSDS) from liquid nitrogen supplier.
