标准范围

ISO 6326-1:2007简要介绍了可用于测定天然气中硫化物的标准化方法。概述了每种方法的原理，指出了该方法适用的浓度范围，并给出了每种方法的分析范围和精密度。它应该使用户能够明智地为正在考虑的应用程序选择合适的方法。进行硫分析是为了确定总硫、特定基团[例如硫醇（硫醇）]中所含的硫、单个硫化合物和硫化合物的特定基团。硫分析领域可用的标准化方法有:用于总硫测定的Wickbold燃烧法（ISO 4260）；测定总硫的林格纳燃烧法（ISO 6326-5）；测定单个硫化物的气相色谱法（ISO 19739）；测定硫化氢、羰基硫和硫醇化合物的电位法（ISO 6326-3）。

ISO 6326-1:2007 gives a brief description of standardized methods that can be used for the determination of sulfur compounds in natural gas.The principle of each method is described generally, the range of concentrations for which the method is suitable is indicated, and the analytical range and precision of each method is given. It should enable the user to select judiciously the proper method for the application being considered. Sulfur analysis is performed in order to determine total sulfur, sulfur contained in specific groups [e.g. thiols (mercaptans)], individual sulfur compounds and specific groups of sulfur compounds.The available standardized methods in the field of sulfur analysis are the Wickbold combustion method for total sulfur determination (ISO 4260); the Lingener combustion method for total sulfur determination (ISO 6326-5); gas chromatography for determination of individual sulfur compounds (ISO 19739); potentiometry for determination of hydrogen sulfide, carbonyl sulfide and thiol compounds (ISO 6326-3).
