  • Apparatus and method for contactless sampling of solutions and interface to mass spectrometry
    Patent number: 11205566
    Abstract: A method of mass spectrometry is disclosed comprising focusing electromagnetic radiation into a region of a liquid sample 3 below a surface of the liquid sample so as to generate one or more bubbles 4. The one or more bubbles 4 rise to the surface of the liquid whereupon one or more droplets of liquid 6 are emitted from the surface of the liquid sample. The method further comprises directing the one or more emitted droplets 6 towards an inlet of a mass spectrometer 8.
