Head Gapootchenko N.P., Registration Date 31-03-2004 Organization Ukrainian State Researsh Institute for Carbochemistry popup.description2 Trial of the method for the determination of the sulphuric anhydride content in gas after the contact apparatus showed after correcting the sampling process that when the temperature goes and in the presence of moisture down sulphuric anhydride converts into sulphuric acid which is adsorbed on the walls of the gas sampling tube. So it is sufficient to determine the concenrtation of sulphuric anhydride in as oprating apparatus by a calculation method based on the content of sulphuric anhydride and the degree of contacting. The method for determining sulphuric anhydride recommended by NIUIF and based on absorption by sodium chloride can be used only in the absence of moisture.
