ABSTRACT:
This invention provides a method of analyzing materials, comprising the steps of subjecting a surface of the material to high energy impact by a laser to cause ablation and vaporization such as to generate a gaseous and/or gas-born sample of the material, transporting all or part of the gaseous and/or gas-born sample of the material to a remote analytical apparatus, and analyzing the gaseous and/or gas-born sample of the material at the remote analytical device so as to determine the constituent compartments of the material, together with Apparatus for carrying out this method.
