| Abstract: | A new on-line vapor-generation nebulization (VGN) method is explored for non-metal detection by microwave plasma torch-mass spectrometry (MPT-MS). In the new method, a three-channel “Y” is used to introduce the sample and reactant solutions simultaneously into a nebulizer. The VGN method offers higher sampling efficiency than does simple nebulization and improves sensitivity roughly two-fold for the determination of non-metallic elements. The device is suggested to be of potential benefit also in the determination of species that do not readily form volatile products. |
