Laser-Induced Breakdown Spectroscopy-Capabilities and Limitations

During the past decade there has been intense activity in the field of laser-induced breakdown spectroscopy (LIBS). This activity includes studies of laser ablation and properties of the laser spark, the development of methods to enhance LIBS detection capabilities, and the application of LIBS to specific analysis needs. The unique capabilities of LIBS make it particularly suited for applications that cannot be addressed by conventional analytical methods. Potential applications of the method are numerous and several applications have been realized, resulting in on-line operating instruments. Other applications will require that the method be developed further to improve analytical performance. Here we present an overview of the LIBS method, discussing its many advantages and some important limitations as an analytical method and how these relate to potential applications.
