Macylab：The experimental scheme of icp6800 for the determination of Si, Mn, P, Cr, Mo, Ni and Cu in steel
1. Preface
With the development and application of metal products, it is closely related to human production and life. Therefore, more and more stringent testing standards and requirements are put forward for products and raw materials. Traditional chemical analysis methods can not meet the requirements of daily analysis and testing. ICP-AES inductively coupled plasma atomic emission spectrometer is widely used in the determination of elements in metal industry because of its low detection limit, fast testing speed, high resolution and high accuracy.

Weigh about 0.2-0.5g sample, add a certain amount of nitric acid, heat at low temperature, after the solution is clear, remove and cool to room temperature, transfer it into a 100ml volumetric flask, dilute it to the scale with water, and mix well. |
In order to determine the content of silicon accurately, blank and parallel sample experiments are needed. |
