| Abstract | The successful direct introduction of aqueous slurry samples into a highly efficient TE101 microwave plasma has been demonstrated. Slurry samples from a spray chamber are fed directly into the cavity with no desolvation apparatus. A V-groove, clog-free Babington-type nebulizer was evaluated for use with high solids content solutions. Slurry concentrations up to 10% Full-size image (<1 K) were used for the microwave induced plasma work with calibration by the standard additions method. Results are presented for the analysis of two NRCC Standard Reference Materials, i.e. TORT-1 (Lobster Hepatopancreas) and PACS-21 (Marine Sediment). Agreement between analytical results and certified values for the test elements Cd, Cu, Fe and Zn (in the range of 28–850 Full-size image (<1 K)) was good. No memory effects were evident and the nebulizer system had a rapid clean-out time. |
