laserflasanalyse

Laserflasanalyse is a method used for the quantitative determination of trace elements in solid samples. The technique involves the vaporization of a small sample by a laser beam, followed by the atomization of the vaporized material. The resulting atoms are then excited by a second laser pulse. The characteristic light emitted by these excited atoms as they return to their ground state is measured by a spectrometer. The intensity of this emitted light is directly proportional to the concentration of the specific element present in the sample. This allows for the precise quantification of a wide range of elements, often at parts per million or even parts per billion levels. Laserflasanalyse is particularly advantageous due to its minimal sample preparation requirements, its ability to analyze small sample sizes, and its potential for in-situ measurements. It finds applications in various fields, including materials science, environmental monitoring, geology, and archaeology, where the elemental composition of solid materials needs to be accurately assessed. The selection of laser parameters, such as wavelength and pulse energy, along with the detection system, are crucial for optimizing sensitivity and accuracy in the analysis.
