摘要： 设计并建立了热喷雾器及其去溶装置．用热喷雾作为电感耦合等离子体原子发射光谱的进样技术,并对其性能作了系统研究．与气动雾化器比较,对23个元素检出限的改善为5～20倍．

关键词: 电感耦合等离子体原子发射光谱, 热喷雾, 样品进样技术

Abstract: Asample introduction system, thermospray nebulizer was coupled to an induc-tively coupled plasma atomic emission spectrometer.The optimization procedure includes the ICP operation conditions, the capillary temperature, the sample uptake rate, aeroso1 spraychamber temperature and the cooling water temperature.Under optimized conditions, thesensitivity for 23 elements obtained with the thermospray system is 14～25 times higher thanwith a pneumatic nebulizer- The thermospray systems have been shown to improve detectionlimits an Order of magnitude lower than that obtained with Pneumatic sample introduction.

Key words: ICP-AES, Thermospray nebulizer, Sample introduction
