Warning: Personnel using this standard should have experience in regular laboratory work. This standard does not address all possible safety issues. Users are responsible for taking appropriate safety and health measures and ensuring compliance with the conditions stipulated in relevant national regulations. Scope: This part of YS/T 281 specifies the determination method for the content of impurity elements such as arsenic, cadmium, copper, zinc, lead, bismuth, tin, antimony, silicon, manganese, iron, nickel, aluminum, and magnesium in cobalt. This section applies to the determination range of the above-mentioned impurity element content in cobalt as follows: For the determination working curve that meets the requirements of this standard, the lower limit of analysis of each impurity element is 80% of the lowest content of the standard sample used, and the upper limit of analysis is 80% of the lowest content of the standard sample used. 120% of the highest content; for parts of the working curve that meet the requirements, select the part of the working curve that meets the requirements of this standard to determine the analysis range of each impurity element. This section specifies objective criteria for evaluating analytical values obtained from arc-type emission spectrometer instruments. Due to the wide range of existing spectroscopic instruments and equipment, it is difficult to completely specify all conditions of spectroscopic equipment. Therefore, this section is not used to specify the model of the instrument or the procedure for converting the response of the instrument into concentration units.
