GB/T 8647.7-2006 《The methods for chemical analysis of nickel - Determination of arsenic,antimony,bismuth,tin and lead contents - Electrothermal atomic absorption spectrometric method》 Related products

GB/T 8647.7-2006 The content of arsenic, antimony, bismuth, tin and lead in nickel is determined by electrothermal atomic absorption spectroscopy (AAS). The standard specifies the pre-treatment process of nickel samples to convert the target element into a detectable state. The element atomization is made by an electrothermal device, and the light spectrum meter measures its absorption of specific wavelengths of light, that is, Absorbance. According to the standard Linear dispersion corresponding to each element, the content is accurately calculated by Absorbance. From sample preparation to result calculation, the whole process is strictly standardized, providing reliable technology for mass detection of nickel products, helping related industries to control product mass, and is widely used in nickel production, processing and other fields.
