A study of microwave induced plasmas

In a microwave induced plasma (MIP) generated in argon under atmospheric pressure using slab-line and TM 10 cavities, the electron density (Ne), excitation and rotational temperatures, detection limit and matrix factor for nine elements and microwave impedance have been determined for a range of operation conditions. Simultaneous measurement of Ne and microwave impedance in a dry argon MIP provide little evidence of a link between these two parameters in the slabline cavity. Two 'analytical' MIP's incorporating sample aerosol introduction have been used with the slab-line cavity. One being supported on an argon flowrate of 0.1 1 min-1 using a Babing!qn nebulizer, the other on a flowrate of 1.0 1 min-1 using a crossflow nebulizer. The crossflow nebulizer was also used for an analytical MIP generated in a TM 010 cavity.
