Claim 31:
32. An air cooled inductively coupled plasma mass spectrometer (ICP-MS), the air cooled ICP-MS, comprising:
a) a sample introduction system;
b) an ICP ionization source, comprising of a plasma torch and a torch housing to generate a plasma;
c) an air cooled interface having a front surface that is exposed to a high temperature plasma, a structure configured to have a heat transfer with air, and a sampling orifice, which takes an ion beam into a mass spectrometer (MS), configured to provide cooling to control heat dissipation while directing heat toward a predefined regions of the air cooled interface to keep the ion beam at a predefined temperature to avoid recombination and clustering, and
d) wherein the heat transfer is induced by one or more of a natural convention, a forced convection or a thermal radiation, and using one or more air fans.
