ABSTRACT:
An improved process for quantitatively determining nitrogen content or other elemental content in a wide variety of materials. The process avoids the use of conventional catalysts, is simpler and faster than previous techniques, and results in a very high degree of accuracy. The process involves the use of a hydrogen peroxide which is added to the digest continuously, while the digest is boiling, while refluxing with a fractionating column. The digestion process also enables quantitative determination of various elements other than nitrogen.
