| 摘 要： | 介绍了一种新型固体粉末进样装置,它由样品气溶胶喷射系统、高频火花雾化控制电路等部分构成,并阐述了装置的工作原理和结构设计。通过对化探样品中痕量B、Pb、Sn和Ag等元素的对比测定试验表明,利用新研制的进样装置代替原来的双高频火花雾化进样器,可使单样平均残留率由原先的26.7%降到0.79%;对比试验表明,方法的精密度(RSD,n=12)由原先的4.31%～6.81%提高到2.37%～3.43%。

| Abstract: | A new sample introduction device used for emission spectral analysis has been developed.It is composed of aerosol injection system and high frequency spark atomization control circuit.The working principle and structural design of the device are presented.The device has been successfully applied to the determination of trace boron,lead,tin and silver in geochemical exploration samples.The new system provides an effective way to reduce sample residues in spark atomization from 26.7% to 0.79%.And the analytical precision (RSD,n=12) is also improved from 4.31%～6.81% to 2.37%-3.43% for these elements. |
