Abstract

The invention discloses an on-line digestion and detection device for total nitrogen content in a solution, which comprises a light source, a digestion device, a reflex condenser, a sampling detection mechanism, and a light guide stick, wherein a top end of the digestion device is connected with the reflex condenser; the outer surface of the digestion device is provided with a heating device; thelight guide stick is inserted into the digestion device and the reflex condenser; the upper end of the light guide stick corresponds to a detection disk of the sampling detection mechanism, and the lower end of the light guide stick corresponds to the light source. The invention is the on-line digestion and detection device for the total nitrogen content in the solution which has a simple and compact structure, low cost, simple and convenient operation, high measurement accuracy, and quick measurement speed.

Description

technical field [0001] The invention mainly relates to the field of detection equipment for nitrogen content in a solution, in particular to an online digestion and detection device for total nitrogen content in a solution. Background technique [0002] In the fields of environmental protection, food, medicine and health, etc., it is often necessary to measure the nitrogen content or protein content of the material. The general practice is to first convert the material into a liquid phase, and then convert all the nitrogen in the liquid phase sample into nitrate ions ( NO 3 - ), through the mensuration of nitrate ion concentration, calculate the total nitrogen content in the material to be tested, its reaction principle is as follows: [0003] In an aqueous solution above 60°C, potassium persulfate can be decomposed to produce potassium bisulfate and atomic oxygen. At 120-124°C, atomic oxygen converts the nitrogen of nitrogen-containing compounds in water samples into nit...
