Evaluation of Microwave Plasma Torch (MPT) as an Excitation Source for Determination of Mercury

The microwave plasma atomic spectrometry is an important branch of the plasma atomic spectrometry. Since the first use of microwave induced plasma（MIP） as an excitation source for spectral Chemical analysis by Broida and Chapmanin in 1958, especially the introduction of TM₀₁₀ cavity by Beenakker in 1976 and of surfatron by Moisan in 1979 with which an atmospheric pressure helium MIPcould be obtained, MIPhas received considerable attention as a new excitation source for spectrometric analysis.
