| 摘 要： | 建立了一种新的热雾化系统，用蠕动泵代替高压泵，去掉了加热管部分，使整个热雾化系统更加紧凑，经济，并将其用于微波等离子体炬（ＭＰＴ）－原子发射光谱法（ＡＥＳ），考察了实验参数的影响，与气动雾化相比，对Ｍｇ，Ｐｂ的检出限改善了５～１０倍，同时发现本装置具有元素选择性增强的现象。

| Abstract: | An improved thermospray system combined with Microwave plasma torch atomicemission spectrometry (MPT-AES) was proposed. The high pressure pump was replacedwith a peristalic pump, and the appendix heating tube was removed, this improvementmakes the thermospray system more compact and economical. The effects of operation pa-rameters on the emission intensity were studied. Compared with pneumatic nebulization, thedetection limits for Mg and Pb of this system were improved to 5 ~ 10 times. And an ele-ment-selected enhancement phenomena was found. |
