Application Note: How to Achieve Low Detection and Quantification Limits for the Nitrogen Determination with Kjeldahl
2 February 2011

This application note indicates that the best results were obtained by using 2% boric acid with 3g potassium chloride per liter. A titration solution of 0.005 M HCl worked best. With these parameters, detection limits for distillation of standard solutions as low as 0.008 mg nitrogen and quantification limits of 0.02 mg nitrogen can be achieved.
