  • Apparatus and methods of use in the mass analysis of chemical samples
    Patent number: 4908512
    Abstract: A probe for supporting a sample in an ion source of a mass spectrometer comprises a target formed by a copper probe tip for a liquid sample in which the sample passes through a fine bore 18a of the tip on to the end surface of the tip where it is held as a droplet by surface tension. In order to replenish the droplet surface, capillary tubing leads from a syringe to the inlet end of the bore in the probe tip.

  • Methods for use in the mass analysis of chemical samples
    Patent number: 4820648
    Abstract: A probe and method for using the same for supporting a sample in an ion source of a mass spectrometer comprises a target formed by a receptacle for a liquid sample in which the sample passes by diffusion to the high vacuum side of a semipermeable membrane and/or in which the sample is held as a droplet by surface tension. In order to replenish the droplet surface, the supply can be arranged to overflow the receptacle.
