Qualitative and quantitative analysis of gases
Thread Content
Hello everyone, I would like to ask you a question here. What methods can be used for the qualitative and quantitative analysis of the exhaust gases generated during the production of carbon-carbon composites? For the CVD process used in the preparation of carbon-carbon composites, natural gas is used as the process gas and nitrogen is used as a diluent gas; the composition of these exhaust gases is unknown. Thank you all.
