Abstract
An interface for coupling hydraulic high pressure nebulization (HHPN) with microwave induced plasma (MIP) atomic emission spectrometry (AES) is described. An appropriate spray chamber and aerosol desolvation system has been constructed for matching the HHPN generated aerosol flow with the loading capacity of toroidal argon and cylindrical helium MIP sources. The system has been optimized for aqueous solutions. Nanogram amounts of metals and nonmetals could be detected by the HHPN-MIP-AES technique developed. The HHPN devices are directly compatible with HPLC solvent flow, therefore they can be directly coupled with HPLC separations in aqueous media.
