摘　　要：应用共聚焦技术于激光诱导荧光检测分析,使用新型半导体泵浦固体激光器,构建了激光诱导荧光检测分析系统,利用LabVIEW开发软件处理信号,实现对不同浓度Rhodamine B和荧光素钠样品溶液的测试。结果表明荧光信号峰值明显,对Rhodamine B检出限达到10-9mol/L,溶液浓度与信号峰值呈良好的线性关系。Based on confocal technology, the laser-induced fluorescence detection system with diode pump solid state laser is presented. LabVIEW software is used to process signals. Rhodamine B and FI show that the peak s and there is a linear uorescein Sodium as the samples are detected ignal value is distinct, and the detection limit of relation between the consistence of samples and by the system. The results Rhodamine B is 10^-9 mol/L, the peak signal value.
