DETAILED DESCRIPTION

[0033] In order to make the purpose, features and advantages of the application more obvious and easy to understand, the application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the application.

[0034] It should be noted that the halogen detection device is an analytical instrument used to detect whether a sample contains halogen elements. Halogen elements include fluorine, chlorine, bromine, iodine and astatine. These elements are widely present in nature and have important applications in certain industrial and medical fields. Halogen detection devices are usually based on techniques such as chemiluminescence, electrochemistry or mass spectrometry. These techniques can detect the presence of halogen elements in a sample and determine their content. Halogen detection devices are widely used in environmental monitoring, food safety, drug testing and industrial analysis. For example, in environmental monitoring, halogen detection devices can be used to detect the halogen content in water, air and soil to assess environmental pollution. In food safety, halogen detection devices can be used to detect halogen residues in food to ensure food safety. In drug testing, halogen detection devices can be used to detect halogen components in drugs to ensure the quality and efficacy of drugs. In industrial analysis, halogen detection devices can be used to detect the halogen content in industrial products to ensure the quality and performance of products. In summary, halogen detection devices are an important analytical instrument widely used in various fields to detect and determine the presence and content of halogen elements in samples.

[0035] The inventors found through analysis of the prior art that halogen detection devices are used to detect all halogen gas leaks below the level of 2.8g / yr. The halogen detection in the existing market is usually based on chemiluminescence method, which uses the reaction of halogen with specific chemicals to generate light signals, and determines the content of halogen by detecting the intensity of light signals. However, the chemiluminescence method has poor selectivity, low sensitivity, high requirements for operator operation, and environmental impact, and requires appropriate safety measures and waste liquid treatment.

[0036] Chemiluminescence method may respond to a variety of elements or compounds, resulting in poor selectivity. Other elements or compounds may interfere with the accurate detection of halogen. Although the chemiluminescence method has high sensitivity, in some cases it may not reach the required detection limit, especially in complex samples. The sample may require complex pretreatment steps such as digestion, separation and purification, which may introduce additional errors and complexity. Chemiluminescence analysis usually requires expensive instruments and equipment such as luminometer or spectrophotometer, which have high cost and maintenance cost. Highly professional knowledge and experience are required to operate chemiluminescence analysis to ensure the accuracy and reliability of the results. The entire analysis process, including sample preparation and detection, may require a long time, which may not be suitable for situations requiring quick results. Some chemiluminescence reactions may produce harmful by-products, affecting the environment, and appropriate safety measures and waste liquid treatment are required.

[0037] It should be noted that, as Figure 7As shown, the principle of the application is to detect the principle that high-energy X-rays excite atomic electron shells, causing the outer electrons of the atomic nucleus to jump, resulting in the release of secondary X-ray energy. Because the energy released by different elements has different characteristics, the detection system measures the energy and quantity, thereby calculating the element content.

The control assembly 6 analyzes and the LED display 9 displays the results. The principle used in the present application is that high-energy X-rays excite atomic electron shells, causing the outer electrons of the atomic nucleus to jump, resulting in the release of secondary X-ray energy, because the energy released by different elements has different characteristics, the detection system measures the energy and quantity, thereby calculating the element content.
