使用 5100 SVDV ICP-OES 对地质样品中的Cu金属进行超快速测定

Traditionally, geological samples are analyzed using flame atomic absorption (FAAS) and/or radial ICP-OES with a vertical torch. Achieving high sample throughput at a low cost per analysis for geochemical samples can be challenging when using these techniques. The samples often have a wide range of element concentrations, requiring multiple dilutions, particularly when using FAAS. The samples also have high levels of total dissolved solids (TDS), which requires frequent cleaning of the sample introduction system. In this application note, the Agilent 5100 Synchronous Vertical Dual View (SVDV) ICP-OES was used to analyze geochemical samples containing up to 2.5% TDS. As well as demonstrating the accuracy and flexibility of the instrument, the sample measurement rate and argon consumption per sample were determined.
