Abstract:
Iron-containing compounds can be problematic during the refinery of petrochemicals or the manufacture of semiconductor devices. These Iron compounds, including particles, can lead to corrosion of refinery equipment, adversely affecting the petroleum value chain. In the semiconductor industry, Fe Nanoparticles (NPs) can lead to cone defects on the surface of wafers, which cause shorting of electrical signals. Single particle inductively coupled plasma mass spectrometry (spICP-MS) is increasingly used to study NPs. Currently, most studies have focused on NPs in aqueous sample matrices, with few studies on nonaqueous matrices. One of the issues for this is the lack of hydrocarbon matrices, and solvent-compatible reference nanomaterials (RMs) to validate new methods. Two gold (Au) polystyrene-coated NP RMs in toluene and silica-shelled iron oxide (Fe3O4) alkylsilane-modified NPs in o-xylene were synthesized. spICP-MS and transmission electron microscopy (TEM) were integral to developing and characterizing the standard materials.
In this talk, we will share the spICP-MS method on the Agilent 7900 ICP-MS used to characterize the synthesized Au and Fe NP RMs. NIST crude oil standard reference material (SRM) and a NIST residual fuel oil SRM were also measured for the natural Fe NP content and spiked Fe NP content.
