in several ways, depending on the original rocks and the elements to be determined. In this document, we present two types of sample preparation. The first uses hydrofluoric acid with boric acid for passivation and the second is a fusion procedure. Sample analysis results, including detection limits, are presented for both sample preparation techniques. 高性能ICP光谱仪
