The GB/T 7043.1-2001 standard focuses on the determination of copper content in rubber. It uses atomic absorption spectroscopy (AAS) to pretreat the rubber sample and convert the copper element into a solution state. Then, with the help of AtomicAbsorption Spectroscopy, the absorption characteristics of copper element to specific wavelengths of light are used to accurately measure Absorption, and then calculate the copper content in rubber. The standard provides an accurate method for measuring copper content in rubber production, mass control and other links, which helps to ensure the mass of rubber products. It is widely used in rubber-related industries for testing work.
