Simulation of nebulization process in inductively coupled plasma atomic emission spectrometry with a modified model using the Monte Carlo technique

Abstract

An improved Monte Carlo program based on a jet model for the simulation of various particle loss processes that occur in the spray chamber is presented. This program is evaluated by comparing the simulated mass transport efficiency and total mass transport rate with those found by experiment. The aerosol flow velocity distribution, as a function of axial and radial distances of the chamber, is outlined. The effect of carrier gas flow rate on the distribution of loss particles along the chamber due to various loss processes is studied. The results indicate that the predominant loss mechanism depends strongly on the magnitude of the carrier gas flow rate.
