應用

• Environmental Monitoring of Heavy Metals: Germanium ICP standards play a crucial role in the preliminary screening of soils for natural radioactivity and metal(loid) content, particularly around decommissioned industrial sites. This application highlights the importance of high-purity germanium standards in environmental health research to ensure community safety and regulatory compliance (Huang et al., 2022).


• Improvement of Iodine Analysis Methods: The reliability of AOAC Official Method 2012.15 for iodine, which often employs germanium as an internal standard in ICP-MS analyses, underscores the standard′s role in enhancing methodological accuracy in biopharmaceutical applications. This improvement is crucial for ensuring the quality and safety of pharmaceutical products (Hieda et al., 2022).


• Advancements in Photochemical Vapor Generation: Research on the synergistic effects from cobalt/chloride ions and air-liquid interfaces in the generation of germanium hydrides showcases the germanium ICP standard′s application in developing novel analytical techniques. This method provides a more efficient and sensitive approach to trace metal analysis in complex matrices (Yu et al., 2022).


• Serum Lithium Quantification: Germanium ICP standards are pivotal in the standard addition method for quantifying serum lithium via inductively coupled plasma mass spectrometry. This technique is essential in clinical biochemistry for monitoring therapeutic levels of lithium, demonstrating the standard′s role in clinical diagnostics (Fan et al., 2022).


• Environmental Water Analysis: The speciation of germanium in environmental water using hydride generation and ICP-MS/MS indicates the utility of germanium ICP standards in environmental science. This method helps in the accurate and sensitive determination of germanium levels, vital for assessing pollution and its ecological impacts (Garcia-Figueroa et al., 2021).
