Abstract:
Analysis on new and used wear-metals oil samples encounter several common issues; determining 30+ important metals by ICP in hydrocarbon matrices, application variables (matrix-matching, metallo-organic standards composition, time between preparation/analysis, etc.) must be minimized (ICP being more sensitive to factor variability).Our experience shows evaluating the individual metal and overall blend is required for elucidating oil/solvent applications. Many metals are relatively “well-behaved”, others produce determination issues; boron’s known analysis challenges relate to elemental form, specific solvent dilution(s), and storage conditions. Our presentation shares impact data of these factors, and discusses the solution-phase chemistry of metallo-organic stock blends with improved analyses.
