I do not know about the ICP specifications, but I know that when I have run
TiOx nanoparticles of 5-10nm in size (across an edge) I had to put HF
directly on the sample and then heat the sample in order for it to fully
dissolve, and this process took overnight. If your particles are smaller,
perhaps it won't take as much time/heat in order to dissolve them.
