A Semimicro-Kjeldahl Method for the Determination of Total Nitrogen in Milk

Method performance study of the determination of total nitrogen in soy sauce by the Kjeldahl method.

The objective of this collaborative study was to evaluate the proposed method for determining the total nitrogen in soy sauce by the Kjeldahl method submitted to the Codex Alimentarius Commission for endorsement in accordance with the protocol for the design, conduct, and interpretation of method-performance studies. The digestive conditions of the proposed method are the addition of 10 mL of H...

A method for determining total nitrogen in Kjeldahl digestion solution using a centrifugal analyser

Adaptation of the Micro-kjeldahl Method for the Determination of Nitrogen in Plant Tissues.

The micro-Kjeldahl method for nitrogen determination has been widely used in organic chemistry laboratories in recent years. The value of this method, developed through the brilliant researches of PiLcH, BANG, PARNAS and WAGNER, PREGL, and coworkers, has justified its application to industrial and clinical problems. Plant physiologists have not generally adopted quantitative micro-methods for n...

Semimicro method for the determination of salicylate levels in blood.

WIDE VARIETY OF METHODS are available for the determination of salicylate in body fluids and tissues. These range from the spot test type used at the patients’ bedside to the organic solvent partition methods employed in more exact studies. In recent years, the method of Brodie et al. (1) involving extraction with ethylene chloride has gained widespread acceptance. The method commonly employs 1...
