from pesticides, petrochemicals, perfumes, to paints, chemical products and their derivatives are ubiquitous. the chemical industry is highly complex, requiring the use of precise equipment, sometimes accompanied by challenging and hazardous logistics. chemical products play a crucial role in our daily lives. controlling the quality of chemical raw materials and improving the quality of chemical products is the primary task to ensure people safely use chemical products.
conducting quality inspections on chemical products is a highly crucial step. it ensures the smooth production of chemical goods, promptly eliminates potential dangers during reactions, and guarantees that all products leaving the factory meet the required standards. chemical analysis is an indispensable part of the chemical industry.
the detection of chemical products involves analyzing formulations to enhance existing technologies for companies. this process not only facilitates innovation for existing products and acquiring intellectual property rights but also identifies and resolves issues during production. through improvements and development in formulation via chemical testing, companies can accelerate the pace of product upgrades, thereby enhancing their market competitiveness.
during inspection work, there's often a multitude of materials to test. hence, it's crucial to scientifically extract samples from batches of products for inspection. the scientific method of sample extraction directly impacts the authenticity and representativeness of the product quality inspection results. moreover, testing both homogeneous and non-homogeneous chemical materials requires analysis results that represent the average composition of all materials.
