The development speed and scale of the chemical industry have a direct impact on various sectors of the social economy. Due to the large number of chemical industry industries, complex processes, and diverse products, the types of pollutants emitted during production are large, large, and highly toxic. Therefore, the chemical industry is a large polluter. . At the same time, chemical products may produce a large number of toxic substances in various links such as processing, storage, use and waste disposal, which affect the ecological environment and endanger human health.

Because the chemical industry is involved in a wide range, almost all laboratory analytical instruments are used for testing in the chemical industry. Common detection indicators in the chemical industry include: chemical additive formulation analysis, metal and mineral detection, chemical material component analysis, polymer and nano-material analysis, textile testing, chemical and physical testing, material aging testing, and hazardous substance testing.
