Abstract
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.
 
A sample introduction system, thermospray nebulizer was coupled to an induc-tively coupled plasma atomic emission spectrometer.The optimization procedure includes theICP operation conditi0ns, the capillary temperature, the sample uptake rate, aeroso1 spraychamber temperature and the cooling water temperature.Under optimized c0nditions, thesensitivity For 23 elements obtained with the thermospray system is 14--25 times higher thanwith a pneumatic nebulizer- The therm0spray systems have been shown to improve detectionlimits an 0rder 0F magnitude lower than that obtained with Pneumatic sample introduction.
