GB/T 20255.2-2006 Determination of cobalt, iron, manganese and nickel in cemented carbide by flame atomic absorption spectroscopy (AAS). The standard specifies the pretreatment steps of the sample to convert these elements in the cemented carbide into a solution state. The elements are atomized with the help of the Flame atomization device, and their absorption of specific wavelengths of light is measured by the Light spectrum instrument. The content of each element is accurately calculated according to the pre-built standard Linear dispersion. From sample preparation to result analysis, there are strict specifications in all aspects. The standard provides a key means for the mass control of cemented carbide and is widely used in cemented carbide production, testing and other related industries.
