Abstract:
A method for spectroscopy of the optical emission of a liquid excited by a pulsed laser focused on the surface thereof is such that the area of analysis is scanned by a laminar discharge of gas whose velocity and section are such that it is possible to remove the residues of the plasma suspended in the gas, resulting from a first laser pulse, before the subsequent laser pulse occurs.
Abstract:
The invention relates to a method for the qualitative and quantitative analysis of samples by optical emission spectroscopy with laser excitation (18), using a database created on single-element aqueous solutions all having the same pure element concentration, this database containing, for each element, the wavelengths of the emission lines and their respective intensities.
Abstract:
The invention relates to a kit for detecting β-radiation on a solid surface in a manner that is not destructive to the solid surface, said kit including at least two films that are sensitive to at least two different types of radiation, including the β-type.
