Analyzer sample gas treatment
Thread Content
90% of the sample gas is steam, which needs to be condensed; however, the analysis medium is dichloromethane. How can the steam be removed while still retaining dichloromethane?
Can it be fully condensed and the liquid analyzed? Or inject directly, using a desiccant to absorb the vapor.
The boiling point of dichloromethane is around 40 degrees, so this sample needs to be condensed. Does the poster want to analyze the content of dichloromethane in the entire sample, or use dichloromethane as the sample to analyze the impurities contained within it? It is best to clarify the detailed analysis requirements, as the sample processing procedure is also related to the analysis indicators and content.
