Abstract
A laser-produced plasma is generated from a copper target using a nitrogen laser. The plasma is formed in air at atmospheric pressure. The temporal characteristics of the plasma are studied by atomic emission spectrometry. The features of the spectra such as the type of lines and the line broadening are described and compared to those obtained at reduced pressure or in other gases. As self-absorption is predominant when the plasma first forms, a time delay is required to obtain the best analytical performance. Limits of detection in the range of 1 – 10 ppm are obtained for copper.
