| 摘 要： | 热雾化法自问世以来 1 ,2 ] ,就以其较高的雾化效率及传输效率受到学者们的普遍重视 .最近 Bordera等3] 提出了一种新的热雾化系统 (该系统采用聚焦微波炉作热雾化系统中液体样品的热源 ,即微波热雾化系统 ,简称 MWTN) ,同时还考察了实验变量对雾滴粒径分布的影响 ,并预期 MWTN具有较高的雾化效率 .本文所提出的热雾化系统与 Bordera等所建立的 MWTN系统在原理上虽然相同 ,但由于采用了新的微波器件 ,所需功率大大降低 ,因此 ,是一种新的低功率 MWTN系统 .在本实验中 ,我们对酸的浓度、载气流量、样品提升量等参数对 Mg的发射强度…

| Abstract: | In this paper, a novel low microwave powered thermospray system was developed. In this system the focused microwave oven used in traditional microwave powered thermospray nebulizer was replaced with a TM 010 microwave resonant cavity, the high pressure pump was replaced with a peristaltic pump. This improvement makes the thermospray system more compact and economical. The influence of several experimental variables(concentration of acid, sample uptake rate, carrier flow rate) on the emission intensity of Mg was evaluated. Compared with the pneumatic nebulization, the detection limits for Mg of this system was improved by a factor of 4. |
