Nanotechnology Single-walled carbon nanotube volatile component testing Evolved Gas Analysis/Gas Chromatography-Mass Spectrometry1 ScopeThis document describes a method for characterizing evolved gases from single-walled carbon nanotube samples using evolved gas analysis/gas chromatography-mass spectrometry. Note. Due to the influence of heating and the possible presence of catalysts, the qualitative and quantitative results of the emitted gas may differ from the gas contained in the sample.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document. ISO /T S80004-3 Nanotechnologies Vocabulary-Part 3.Carbon nano-objects Part 3.Carbon nano-objects) GB/T 30544.3-2015 Nanotechnology Terminology Part 3.Carbon Nanoobjects (ISO /T S80004-3.2010, IDT)3 Terms and definitionsThe terms and definitions defined in ISO /T S80004-3 and the following apply to this document. The URLs for terminology databases used for standardization maintained by ISO and IEC are as follows. 3.1 Single-walled carbon nanotube; SWCNT A carbon nanotube consisting of a cylindrical carbon monolayer. [Source. GB/T 30544.3-2015, 4.4] 3.2 Evolved gas analysis; EGA A method for qualitatively and/or quantitatively measuring the functional relationship between the volatile products released from a sample and the temperature under programmed temperature control. [Source. GB/T 30544.6-2016, 4.24, modified] 3.3 evolved gas analysis/mass spectrometry; EGA/MS A technique that uses mass spectrometry to analyze how the gas components released from a sample change with temperature. Note. Although multiple evolved gases can be detected simultaneously at a specific temperature, the different components cannot be uniquely identified using mass spectrometry alone. 3.4 evolved gas analysis/gas chromatograph-mass spectrometry; EGA/GCMS A technique that combines gas chromatography and mass spectrometry to analyze the chemical composition of gases evolving from a sample at different temperatures. NOTE. The evolved gases are passed through a gas chromatograph (GC) to separate each component for identification in a mass spectrometer (MS) unit. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GBZ45113-2024_English be delivered?Answer: Upon your order, we will start to translate GBZ45113-2024_English as soon as possible, and keep you informed of the progress.
