ABSTRACT
We have recently derived a useful set of scaling laws for the operating parameters of the high-pressure inductively coupled plasma torch and have verified the validity of our results by performing numerical simulations of inductively coupled plasmas of varying diameters, assuming local thermodynamic equilibrium conditions. In this contribution, we present complementary non-equilibrium simulations to demonstrate that our scaling laws hold even when departures from equilibrium are important.
