Assessment of Detectable Elements
Sample | Elements Measured | Apparatus | Sample Preparation Overview | Remarks |
Metal Material | Si, Mn, P, Cr, Mo, Ni, Cu | HKL-17650 ICP for Determination of metallic element content in steel | Weigh approximately 0.2-0.5g sample, add a certain amount of nitric acid, heat at low temperature. After the solution becomes clear, cool to room temperature and transfer to a 100ml volumetric flask. Dilute to volume with water and mix well. | Blank and parallel sample tests are required for accurate determination of Si content. |
