First, the definition of halogens

Halogen, short for halogen elements, is the VII.A element on the periodic table, including fluorine, chlorine, bromine, iodine, hey and other five elements. Because it belongs to radioactive elements, people often say that halogens refer to fluorine, chlorine, bromine, and iodine.

Second, the harm of halogens

Halogens are extremely harmful, toxic to the immune system, effects on the endocrine system, effects on reproduction and development, carcinogenic effects, other toxicities (mental and psychological disorders), most halides are environmental hormonal substances

According to many scientific studies, halogenated flame retardants have become a pollutant that spreads everywhere in the daily environment and pose an increasing threat to the environment and human beings. The act of manufacturing, recycling, or discarding appliances and other consumer products is the main way these pollutants are released into the environment. In order to protect the environment, various laws and regulations have also appeared to limit the use of halogens. Some halogenated flame retardants can no longer be used in the plastic materials of electrical products and building materials (this generally refers to the surface/shell of plastics). The reason why halogen-based flame retardants are banned in plastic materials is that such flame retardants cannot be recycled, and harmful substances are released during combustion and heating, threatening human health, the environment and future generations.

At present, on the basis of DX-320L, the new analytical instrument DX-320L(H) has been successfully developed, using the electronic circuit unit with high signal-to-noise ratio and the X-fluorescence analysis software for halogen testing. The DX-320L(H) Halogen Test Accessory was developed for testing halogen group elements, especially chlorine. After many experimental halogen-free analysis data analysis, the results of halogen-free analysis are very close to the standard value, DX-320L(H) can be widely used in various types of halogen-free testing.

Instrument introduction

DX-320L X fluorescence spectrometer is a rapid and accurate analysis of complex components and multiple types of palmetto elements in domestic cement plants and steel companies using XRF technology. The main features of this technology are: the use of low-energy X-ray to excite the elements to be measured, which has a good excitation effect on light elements such as Si, S, AI, Na, Mg, etc., and the test time is short, which greatly improves the detection efficiency and work efficiency; UHRD detector is adopted, which has good energy linearity and energy resolution, good energy spectral characteristics, and high peak-to-background ratio; The automatic spectrum stabilization device is adopted to ensure the consistency of the instrument work; The spectral peak decomposition technology is used to make the analyzer using UHRD detector have the analysis accuracy of light elements such as Si, S, and AI. Similar automatic classification technology is used to make classification more accurate and effectively overcome the influence of base effect on measurement; The multi-parameter linear regression method was adopted to significantly eliminate the absorption and enhancement effects between elements.
