US Patent 11247295 Methods for multiphase laser ablation analysis

Methods of liquid and solid materials analysis by laser induced ablation spectroscopy are disclosed. The liquid and solid materials are analyzed in an instrument having one pulsed laser to produce emissive plasma plumes and ablate solid material. Liquid phase samples are aerosolized before streaming to an analysis zone where they are dissociated into a plasma plume. A large number of sites within solid phase sample structures and be analyzed using a movable x-y-z stage and displayed in a chemical map.
