GB/T 20255.5-2006 《Methods for chemical analysis of hardmetals - Determination of chromium content - Flame atomic absorption spectrometric method》 Related products
GB/T 20255.5-2006 Introduces the determination of chromium content in cemented carbide by flame atomic absorption spectroscopy (AAS). Sample Handling of cemented carbide is first used to dissolve chromium to form a solution. Flame atomization is used to measure the absorption degree of chromium atoms to specific wavelengths of light, that is, Absorbance. According to the pre-established standard Linear dispersion, the chromium content is accurately calculated by Absorbance. This standard provides key technology for the mass detection of cemented carbide, which helps to determine whether its composition is up to standard, and helps to optimize the production process. It is widely used in cemented carbide production, inspection and machinery manufacturing and other related industries.
