Simultaneous microdetermination of carbon, hydrogen and chlorine or bromine in organic compounds by various rapid empty-tube combustion methods.
A standard Pregl absorption tube packed with polyurethane foam mixed with a cation-exchanger in the silver form, backed with a layer of "Anhydrone", and connected between the water and carbon dioxide absorption tubes and kept at room temperature, has been employed successfully for the simultaneous determination of chlorine or bromine together with carbon and hydrogen. This foam tube is suitable for use with the Belcher-Ingram, rapid straight empty-tube and rapid flash-combustion methods.
