摘要：

Laser-induced plasma spectroscopy (LIPS) was applied to direct multi-element analysis of chemical species in a hydrogen-air diffusion flame. The plasma was generated by focusing the second harmonic radiation from a Nd:YAG laser at a wavelength of 532 run and the resulting plasma emission was detected by a multi-channel spectrometer. The spatial profiles obtained by LIPS measurements for the atomic emission intensities of hydrogen and oxygen, normalized by that of nitrogen, were in good agreement with those of numerical simulation. The present results show that LIPS has a high potential for the quantitative elemental analysis of chemical species in a flame. (C) 2001 Elsevier Science B.V. All rights reserved.
