IEC TS 62607-6-19:20 21(E)建立了确定化学关键控制特性的标准化方法？元素组成对于由石墨烯基材料组成的粉末，？CS分析仪和ONH分析仪。如本文所述的方法测定碳(C)、硫(S)、氧(O)、氮(N)和氢(H)的含量。石墨烯粉末中的碳（C）和硫（S）含量由转化的CO、CO2和SO2的含量导出，其通过红外气体检测器（IGD）在CS分析仪中使用非分散红外吸附法测定。石墨烯粉末中氧（O）、氮（N）和氢（H）的含量由ONH分析仪使用热解方法导出。O含量是根据转化的CO和CO2的含量获得的，其通过IGD使用非-分散红外吸附法。N含量根据换算的N2的含量获得，其通过热导检测器(TCD)法测定。H含量通过测量转化的H2或H2O获得，对应于TCD或IGD方法。？该方法适用于粉末形式的石墨烯、氧化石墨烯(GO)和还原氧化石墨烯(rGO)。

IEC TS 62607-6-19:2021(E) establishes a standardized method to determine the chemical key control characteristic
？ elemental composition
for powder consisting of graphene-based material by
？ CS analyser and ONH analyser.
The method as described in this document determines the content of carbon (C), sulfur (S), oxygen (O), nitrogen (N) and hydrogen (H).
The carbon (C) and sulfur (S) content in graphene powder is derived by the content of converted CO, CO2 and SO2, which is determined by infrared gas detector (IGD) using a non-dispersive infrared adsorption method in CS analyser.
The content of oxygen (O), nitrogen (N) and hydrogen (H) in graphene powder is derived by ONH analyser using pyrolysis method. The O content is obtained according to the content of converted CO and CO2, which is determined by IGD using a non-dispersive infrared adsorption method. The N content is obtained according to the content of converted N2, which is determined by a thermal conductivity detector (TCD) method. The H content is obtained by measuring converted H2 or H2O, corresponding to TCD or IGD method.
？ The method is applicable for graphene, graphene oxide (GO) and reduced graphene oxide (rGO) in powder form.
