One of the main sources of error in the micro determination of carbon and hydrogen is attributable to the lead dioxide used for the removal of nitrogen oxides. Some preparations yield high blanks, and in others the equilibrium between water and carbon dioxide is readily upset even though the reagent
The analysis of organic compounds for carbon and hydrogen continues to be among those in greatest demand in many petroleum and petrochemicals research laboratories. Increasing demands for carbon and hydrogen analyses in this laboratory necessitated a search for a faster, more accurate and more stabl
