  • Patent number: 10540536
    Abstract: Imaging mass spectrometry (IMS) has become a prime tool for studying the distribution of biomolecules in tissue. Although IMS data sets can become very large, computational methods have made it practically feasible to search these experiments for relevant findings. However, these methods lack access to an important source of information that many human interpretations rely upon: anatomical insight. In this work, this need is addressed by (1) integrating a curated anatomical data source with an empirically acquired IMS data source, establishing an algorithm-accessible link between them; and (2) demonstrating the potential of such an IMS-anatomical atlas link by applying it toward automated anatomical interpretation of ion distributions in tissue.

  • Publication number: 20100133098
    Abstract: Analytical methods and devices are disclosed for separating low abundance analytes by electrophoretically driving the analytes through a sieving matrix to first remove high molecular weight species. Subsequently the remaining low abundance analytes are electrophoretically focused onto a capture membrane where the analytes become bound within a small capture site. After this step the capture membrane may be allowed to dry and then attached to a conductive MALDI sample plate.

  • Patent number: 5808300
    Abstract: MALDI MS has been used to generate images of samples in one or more m/z pictures, providing the capability of mapping concentrations of specific molecules in X,Y coordinates of the original sample. For sections of mammalian tissue, for example, this can be accomplished in two ways. First, tissue slices can be directly analyzed after thorough drying and application of a thin coating of matrix by electrospray. Second, imprints of the tissue can be analyzed by blotting the dry tissue sections on specially prepared targets, e.g., C-18 (10 .mu.m dia.) beads. Peptides and small proteins bind to the C-18 and create a positive imprint of the tissue which can be imaged by MALDI MS after application of matrix. Such images can be displayed in individual m/z values as a selected ion image which would localize individual compounds in the tissue, as summed ion images, or as a total ion image which would be analogous to a photomicrograph.

  • Patent number: 5572023
    Abstract: Electrospray equipment and techniques are provided for receiving a liquid solution containing test molecules of interest and solvent and forming ionized droplets of interest for analysis by a mass spectrometer. The flow path within the electrically charged spray needle 16 may be filled with a packing material 20 for adsorbing selected chemicals in the liquid solution before being discharged from the spray needle into a vaporizing chamber 33. The spray needle preferably comprises a fused silica capillary tubing, and the discharge end 25 of the capillary tubing is spaced closely adjacent an exit orifice 31 of the vaporizer probe 12. Inert gas such as pure nitrogen is input to the probe. The techniques of the present invention are particularly well suited for mass spectrometer analysis of low flow rate test material.

  • Patent number: 5078135
    Abstract: The present invention combines microdialysis with mass spectrometry, for example continuous flow fast atom bombardment, to follow the pharmacokinetics of drugs or other compounds directly in the blood stream or tissues of a live animal. After intramuscular injection of the drug, the blood dialysate from a microdialysis probe inserted into a blood vessel or tissue of the animal, is allowed to flow into the mass spectrometer via the continuous flow fast atom bombardment interface. Tandem mass spectrometry allows for isolating and recording the ion fragments produced from the drug as the dialysate is exposed to the ionization process. The detected concentration of the drug or other compounds of interest can be used to adjust the rate of administration of the drug.

  • 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.
