Figure 54, a kind of water quality total nitrogen detection device provided by the present invention, comprises a main frame 1, a circulation pool 2, a plug 3, a pressure plate 4, a light source part 5, and a spectrometer 6. The main frame 1 is in a circular shape, and the circulation pool 2 is arranged in the main frame 1. The circulation pool 2 is used to hold samples and reagents. A resistance wire (not shown) is provided on the outside of the circulation pool 2. The resistance wire is used for heating so that the samples and reagents in the circulation pool 2 undergo a digestion reaction. In order to prevent the circulation pool 2 from leaking at high temperatures, plugs 3 and pressure plates 4 are provided at both ends of the main frame 1 to seal the circulation pool 2. The material of the plug 3 is preferably polytetrafluoroethylene. The plug 3 seals the circulation pool 2 first, and the pressure plate 4 applies pressure to the plug 3 to achieve a better sealing effect. The pressure plate 4 is fixedly connected to the main frame 1 by bolts. The light source part 5 is fixed to one side of the main frame 1 through a light source connecting plate 51 provided on the main frame 1. The light source of the light source part 5 is Xenon lamp light source, xenon lamp light source has a long life, about 10 times that of traditional lamps, and can work for more than 3,000 hours, reducing the frequency of replacing bulbs and reducing maintenance costs. The spectrometer 6 is tilted on the side of the main frame 1 opposite to the light source part 5 through the spectrometer connecting plate 61 arranged on the main frame 1. In order to make the overall structure of the device compact, all components are designed with exquisite design. The size of the designed spectrometer 6 is strictly controlled at 6cm×6cm×3cm, and the test position of the spectrometer 6 is also embedded in the circular main frame 1 that fixes the flow cell 2, which greatly shortens the lateral size of the device. The working principle of the spectrometer 6 adopts the Lambert-Beer law, that is, the energy of the light emitted by the light source part 5 will change after passing through the flow cell 2 with different concentrations. The energy after passing through pure water is recorded as T0, and the energy after passing through the liquid with concentration is recorded as T1. The absorbance is calculated using the formula lg(T0 / T1).

[0027] The following will refer to Figures 1 to 5 The working principle of the present utility model is described.

[0028] Light from light source 5 strikes flow cell 2, where it is collected by spectrometer 6. After being processed by an algorithm within spectrometer 6, the light is output to a host computer for easy access. The spectrometer designed in this utility model is compact and features stable data collection. The flow cell 2 is well-sealed, leak-proof even at temperatures up to 125°C. The xenon lamp used in the device boasts a lifespan of up to 3 billion flashes. The entire device is compact, delivering stable test results and excellent linearity.
