The National Nonferrous Metals and Electronic Materials Analysis and Testing Center has been engaged in the research and development of standard materials, standard samples, pure substances and special reagents since 2006. It is the first in China to develop multi-element mixed standard solutions suitable for use in, and ion chromatography and other instruments. Many The product fills the domestic gap. At present, our center has developed more than 50 single-element standard solutions and nearly ten multi-element mixed standard solutions, and has obtained national standard sample numbers. It has been widely used in the analysis and testing departments of colleges and universities, chemical industry, environmental sanitation, quality supervision, inspection and quarantine, non-ferrous metals, metallurgy and other industries.
