چکیده
A new method for the determination of nitrogen in biologic material is described. It is basedon an improvedashingprocedureand the Berthelot reactton in which nitrogen is converted to indophenol.The concentration of this substance is determined photometrically. The proposedmethod yields the same results as the Keldahi procedure; however, it offers a higher degree of sensitivity combined with the same degree of accuracy. In addition, the determination requires only 4 hr., in comparisonto 24 hr. for the Kjeldahl method.
