Abstract
The application relates to the technical field of detection, and discloses a total nitrogen automatic analysis system. The total nitrogen automatic analysis system provided by the application is used for detecting different total nitrogen concentrations of to-be-detected samples by controlling the output of different liquid volumes of the samples to an optical detection module by a quantitative unit. When the total nitrogen concentration of the to-be-detected sample is high, the quantitative unit outputs a small volume of liquid for detection; when the total nitrogen concentration of the to-be-detected sample is low, the quantitative unit outputs a large volume of liquid for detection, so that the system can detect a wide range of total nitrogen concentrations. When the total nitrogen concentration of the to-be-detected sample is extremely low, the system can have a low detection limit by controlling the output of the liquid volume to the optical detection module by the quantitative unit.
