GB/T 6609.30 - 2009 Focuses on the determination of trace elements in aluminum oxide. It stipulates the use of X-ray Phosphorescence spectrum method to determine the content of trace elements in aluminum oxide. The standard specifies the preparation requirements of the sample to ensure that the sample is uniform and representative. Detailed description of the operating conditions of the X-ray Fluorescence Spectrophotometer, such as instrument parameter settings, measurement environment control, etc. Through this standard, a variety of trace elements in aluminum oxide can be accurately detected. These data are of great significance for evaluating aluminum oxide mass, controlling production processes, and applications in electronics, chemical and other fields, helping enterprises to improve product quality and meet the strict requirements of different industries for aluminum oxide purity.
