ASTM D7649-2010 使用喷吹脉冲注射和气相色谱分析/质谱仪测定氢燃料中痕量二氧化碳,氩,氮,氧和水含量的标准试验方法
简介:Low operating temperature fuel cells such as proton exchange membrane fuel cells (PEMFCs) require high purity hydrogen for maximum performance. The following are the reported effects (SAE TIR J2719) of the compounds determined by this test method. Carbon Dioxide (CO2), acts largely as a diluent, however in the fuel cell environment CO2 can be transformed into CO. Water (H2O), is an inert impurity, as it does not affect the function of a fuel cell stack; however, it provides a transport mechanism for water-soluble contaminants, such as Na+ or K+. In addition, it may form ice on valve internal surface at cold weather or react exothermally with metal hydride used as hydrogen fuel storage. Inert Gases (N2 and Ar), do not normally react with a fuel cell components or fuel cell system and are considered diluents. Diluents can decrease fuel cell stack performance. Oxygen (O2), in low concentrations is considered an inert impurity, as it does not adversely affect the function of a fuel cell stack; however, it is a safety concern for vehicle on board fuel storage as it can react violently with hydrogen to generate water and heat.1.1 This test method describes a procedure primarily for the determination of carbon dioxide, argon, nitrogen, oxygen and water in high pressure fuel cell grade hydrogen by gas chromatograph/mass spectrometer (GC/MS) with injection of sample at the same pressure as sample without pressure reduction, which is called x201C;Jet Pulse Injectionx201D;. The procedures described in this method were designed to measure carbon dioxide at 0.5micromole per mole (ppmv), Argon 1 ppmv, nitrogen 5 ppmv and oxygen 2 ppmv and water 4 ppmv. 1.2 The values stated in SI units are standard. The values stated in inch-pound units are for information only. 1.3 The mention of trade names in standard does not constitute endorsement or recommendation for use. Other manufacturers of equipment or equipment models can be used. 1.4 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.

ASTM C1494-2013 氨化硅粉末中碳、氮和氧的质量分数测定的标准试验方法
简介: 3.1x00a0;These test methods are for the chemical analysis of mass fraction of carbon, nitrogen and oxygen in silicon nitride powder. They are used in research, development, production, acceptance, and quality control of silicon nitride powders used to produce ceramic components with silicon nitride content. 3.2x00a0;It is assumed that all who use these test methods will be trained analysts, capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory. 1.1x00a0;These test methods cover the determination of mass fraction % of carbon, nitrogen and oxygen in silicon nitride powder having chemical compositions within the following limits: Element Mass Fraction % Range x00a0; x00a0; Carbon 0.05 to 5.0 Nitrogen 30 to 45 Oxygen 0.1 to 1.5 1.2x00a0;Two test methods appear in this standard. 1.2.1x00a0;Total Carbon by the Direct Combustion-Infrared Measurement Method. 1.2.2x00a0;Nitrogen by the Inert Gas Fusion-Thermal Conductivity Measurement Method and Oxygen by the Inert Gas Fusion-Infrared Measurement Method. 1.3x00a0;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. Specific hazard statements are given in Section 6.
