The particle size in the environment is smaller than5 mmThe plastic pollutants are called "microplastics", which have complex physical and chemical properties. Microplastics have been found in environments such as oceans, rivers, atmosphere, and soil. With the increasing attention of the country to environmental protection, research on microplastic pollution has become one of the hotspots in recent years. The Ministry of Ecology and Environment 2022 year 3 At the regular press conference held in the month, it was stated that we are currently studying and formulating action plans for the treatment of new pollutants, including microplastics. Water is closely related to our lives. In order to better detect and monitor microplastic pollutants in various types of water bodies, including oceans, rivers, lakes, reservoirs, groundwater, and tap water, Agilent has collaborated with domestic research institutions to develop a solution for water pollution10 μm–5 mmA comprehensive solution for microplastic detection within the particle size range.

Spectroscopy is a commonly used method for detecting microplastics. Among them, Agilent infrared spectroscopy has become an ideal choice for qualitative analysis of microplastics due to its molecular fingerprint spectrum characteristics and detection results that are not affected by particle color. For particles with a lower proportion in the sample and a diameter greater than500 μmFor particles, conventional Fourier transform infrared instruments can be used in combination with attenuated total reflection(ATR)Inspect attachments; And for particles smaller than500 μmThe particles are difficult for the human eye to recognize and require the use of infrared microscopy equipment for detection.
