Dr. John Olesik at Ohio State University pioneered the study of droplets/particulates surviving standard ICP discharges and his early findings were surprising to most. He detected droplets that survived. Do you know how these nanoparticles influence droplet size distribution? You may want to examine ultrasonic nebulization which will shift droplet size significantly to smaller particulates.

Subject: Re: nanoparticles and HF questions
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?
