本文件给出了在惰性或氧化环境中通过热重分析（TGA）对含碳纳米管（CNT）样品进行表征的指南。通过定量测量材料中存在的碳物种类型以及非碳杂质（例如金属催化剂颗粒），提供CNT样品纯度评估指南。交叉引用:ISO/TS 80004-3ISO/IEC指南98-3:2008 Ed 1ISO/IEC 17025购买时可用的所有当前修订版均包含在本文件的购买中。

This document gives guidelines for the characterization of carbon nanotube (CNT)-containing samples by thermogravimetric analysis (TGA), performed in either an inert or oxidizing environment. Guidance is provided on the purity assessment of the CNT samples through a quantitative measure of the types of carbon species present as well as the non-carbon impurities (e.g. metal catalyst particles) within the material.Cross References:ISO/TS 80004-3ISO/IEC GUIDE 98-3:2008 Ed 1ISO/IEC 17025All current amendments available at time of purchase are included with the purchase of this document.
