Abstract
Various experimental conditions for laser-enhanced ionization (LEI) spectroscopy in a graphite furnace are investigated with the aim to find optimal conditions for trace element analysis. Some general aspects of the generation of LEI charges and the collection of the signal are discussed. It is established that many elements can be measured with very high sensitivity and good reproducibility. However, the determination of certain elements probably requires a modified experimental configuration. Such a modification is discussed in the paper.
