Hydrogen Detection in Steel Pins by Direct-EGAMS
Introduction
Recently, efforts are being made to create a decarbonized society as an issue of global environmental conservation, and it is necessary to strengthen the reduction of greenhouse gases such as carbon dioxide. In particular, material industries such as steel and chemicals use a large amount of coal and petroleum in their manufacturing processes, so they emit a large amount of CO2. Especially in the steelmaking process, the utilization of hydrogen is expected. On the other hand, hydrogen embrittlement of steel materials due to hydrogen absorbed in steel materials also exists as a problem, and analytical techniques for confirming the presence of hydrogen in steel materials are required. Therefore, we introduce an analysis example in which the hydrogen generated when steel pins are heated using a pyrolyzer is directly detected by a mass spectrometer.
