激光微探针发射光谱分析(简称激光探针分析),也称激光显微光谱分析,文献上缩写为LMES,是发射光谱分析的一个分支,具有微区取样、微损分析的特长,它是目前微区分析的主要手段之一。通常的发射光谱分析方法,将被分析的样品置于光谱纯石墨电极的孔穴中,用电弧使之蒸发和激发,所发射的光经光谱仪分解为光谱,根据光谱中谱线的波长和强度进行定性和定量分析。这种方法耗样10至30毫克。实际工作中有时不容许损耗这么多的样品,如古董、文物的分析,要求实物经分析后没有肉眼可辨的明显损伤;又如样品上的异
Laser microprobe emission spectroscopy (referred to as laser probe analysis), also known as laser microspectroscopy, literally LMES, is a branch of emission spectroscopy, with micro-zone sampling, micro-loss analysis of the expertise, it is One of the main means of micro-area analysis. The usual method of emission spectroscopy is to place the sample under analysis into the pores of a spectrographically pure graphite electrode, evaporate and excite it with an electric arc, and the emitted light is decomposed into spectra by a spectrometer and wavelength and intensity of spectral lines in the spectrum Qualitative and quantitative analysis. This method consumes 10 to 30 mg. The actual work sometimes does not allow the loss of so many samples, such as antiques, artifacts of the analysis, after physical analysis of the physical no obvious visible damage; Another example of the differences
