激光光谱分析是60年代发展起来的一种新兴技术,尤其是可调谐激光器的出现,使激光在原子光谱分析中的应用获得重大进展。可调谐激光作为光源,可将蒸发、激发和发射分开进行,并可进行调谐激发,以降低背景和减少线宽来提高分辨率和灵敏度,为无机分析开拓了新领域,灵敏度由原子个数代替经典的至今沿用的百分浓度,使分析化学可获得飞跃。一、激光选择探针离子发光荧光光谱激光荧光光谱是一种新的分析技术,十多年来应用较广发展迅速。J. C. Wright等发表了一系列关于激光选择探针离子发光的
Laser spectroscopy is an emerging technology developed in the 1960s, especially the emergence of tunable lasers, making great progress in the application of laser in atomic spectroscopy. Tunable laser as a light source, evaporation, excitation and emission separately, and can be tuned excitation to reduce the background and reduce the line width to improve the resolution and sensitivity for inorganic analysis to open up new areas, the sensitivity of the number of atoms instead of The percentage concentration of the classic so far, so that the analytical chemistry can make a big leap forward. First, the laser selection probe ion-emitting fluorescence spectroscopy Laser fluorescence spectroscopy is a new analytical technique, more than a decade of rapid development of a wide range of applications.
