GB/T 223.53-1987 《Methods for chemical analysis of iron，steel and alloy--The flame atomic absorption spectrophotometric method for the determination of copper content》 Related products

GB/T 223.53-1987 provides for the determination of copper in steel and alloys by flame Atomic absirption spectrophography-tometry, AAS. The standard specifies the test principle and uses the absorption characteristics of copper elements to specific wavelengths of light. Detailed description of the required instruments and equipment, such as the parameter requirements of the atomic absorption spectrophotometer. Describe the sample prepative process, covering sampling, dissolve and other steps. Standardize the test operation, including instrument debugging, measurement wavelength selection, etc. Through this standard, the copper content in steel and alloys can be accurately determined, providing key data support for steel and alloy production and mass control.
