IEC TS 62607-6-20:2022

IEC TS 62607-6-20:2022 (EN) IEC TS 62607 establishes a standardized method to determine the chemical key control characteristic - metallic impurity content for powders of graphene-based materials by - inductively coupled plasma mass spectrometry (ICP-MS). The metallic impurity content is derived by the signal intensity of measured elements through MS spectrum of ICP-MS. - The method is applicable for powder of graphene and related materials, including bilayer graphene (2LG), trilayer graphene (3LG), few-layer graphene (FLG), reduced graphene oxide (rGO) and graphene oxide (GO). – The typical application area is in the microelectronics industry, e.g. conductive pastes, displays, etc., for manufacturers to guide material design, and for downstream users to select suitable products.
