Laser Enhanced Ionization in Flames

摘要

This report describes the discovery of laser enhanced ionization in flames along with a description of research on the mechanisms of signal production and collection. Early experiments on the method's use for complex sample analysis are described. Results of this research predict that two photon-two wavelength laser enhanced ionization will produce detection limits at the 10 parts per trillion level in solution for most elements. Laser excitation provides high selectivity so that the method can be predicted to have high accuracy.
