DERTERMINATION METHOD OF QUANTITATIVE NITROGEN CONTENT OF SOLID MATTER OF SAMPLE AND APPARATUS FOR IMPLEMENTING THE METHOD

摘要

To select a sample of nitrogen content, which was dissolved in the nitrogen free acid in a flask (2), the gas chamber is in communication with a bubble solution (16) in which is collected after addition of alkali metal hydroxide solution in the liquid, of the volatile ammonium compounds which are formed in the balloon, using a reflux condenser (5) and a liquid distributor (4) through which the condensate is returned the balloon and wherein the bubbling vessel (15) is connected to reflux condenser.
