ICP-MS (Inductively Coupled Plasma Mass Spectrometry) is the preferred method for detecting trace gallium (Ga) in environmental and biological samples, often requiring sector field-ICP-MS to overcome interferences from Ba at 69 and MnO at 71. Gallium is typically stable in 1–5% HNO and is dissolved using HCl/HNO mixtures, though it requires specialized sample preparation to manage low concentrations.
PubMed Central (PMC) (.gov) +1Key Aspects of ICP Testing for Vanadium:
Techniques:
ICP-OES is preferred for industrial applications and high-concentration samples due to its robustness and speed. ICP-MS is utilized when extreme sensitivity is needed.
ICP-OES Applications:
Used in analyzing vanadium in catalysts, crude oil, and vanadium redox flow batteries (VRFB).
