Abstract
Portable instruments for analyzing elemental composition of liquid and solid phase materials by laser induced ablation spectroscopy are disclosed. The optical path of a single pulsed laser beam in the instrument is directed to a position depending on the phase of the sample material. Liquid phase samples are aerosolized before streaming to an analysis zone where they are dissociated in a plasma plume. A wide range of physical and chemical characteristics of liquid materials can be analyzed by the instruments. A large number of sites within solid phase sample structures are analyzed using a movable x-y-z stage in the instrument and the results are displayed in a chemical map.
