  • Publication number: 20190348266
    Abstract: The invention generally relates to systems and methods for relay ionization of a sample. In certain aspects, the invention provides systems that include an ion source that generates ions, a sample emitter configured to hold a sample, and a mass spectrometer. The system is configured such that the ions generated by the ion source are directed to interact with the sample emitter, thereby causing the sample to be discharged from the sample emitter and into the mass spectrometer.

  • Publication number: 20190237315
    Abstract: The invention generally relates to zero volt mass spectrometry probes and systems. In certain embodiments, the invention provides a system including a mass spectrometry probe including a porous material, and a mass spectrometer (bench-top or miniature mass spectrometer). The system operates without an application of voltage to the probe. In certain embodiments, the probe is oriented such that a distal end faces an inlet of the mass spectrometer. In other embodiments, the distal end of the probe is 5 mm or less from an inlet of the mass spectrometer.

  • Publication number: 20190219555
    Abstract: The invention generally relates to methods for analyzing stability of an active pharmaceutical agent. In certain aspects, the methods involve obtaining an active pharmaceutical agent, and distributing the active pharmaceutical agent into one or more microdroplets. The one or more microdroplets including the active pharmaceutical agent are then subjected to one or more conditions that force degradation of the active pharmaceutical agent in each of the one or more microdroplets. The one or more microdroplets are then analyzed to determine a ratio of the active pharmaceutical agent to that of a degradation product of the active pharmaceutical agent, thereby analyzing stability of an active pharmaceutical agent.

  • Patent number: 10329679
    Abstract: The invention generally relates to systems and methods for producing metal clusters; functionalized surfaces; and droplets including solvated metal ions. In certain aspects, the invention provides methods that involve providing a metal and a solvent. The methods additionally involve applying voltage to the solvated metal to thereby produce solvent droplets including ions of the metal containing compound, and directing the solvent droplets including the metal ions to a target. In certain embodiments, once at the target, the metal ions can react directly or catalyze reactions.
