Does anyone happen to know whether titanium dioxide nanoparticles survive in an ICP plasma, or do they get broken down to titanium and oxygen? If I were to analyse a solution containing only titanium dioxide nanoparticles in acidified water (which looks like a clear solution to me,) would I need to digest it first to be able to determine the titanium content?
Also, I have a standard P-E Elan9000 ICP-MS with nickel cones and cross-flow nebuliser. Will it be OK to run samples in a dilute HF matrix through it, or do I need to obtain platinum cones or other HF-proof parts?
