    Abstract: The invention generally relates to systems and methods for analyzing a sample from a surface. In certain aspects, the invention provides systems that include a sample introduction member that has an inlet, an outlet, and an opening along a wall of the sample introduction member. The sample introduction member may be configured such that the opening couples with a surface that includes a sample in a manner in which molecules of the sample enter the sample introduction member via the opening and exit the sample introduction member via the outlet. A mass spectrometer is configured to receive the molecules of the sample.

    Abstract: The invention generally relates to sample analysis with a miniature mass spectrometer. In certain embodiments, the invention provides methods that involve generating ions of a first analyte and ions of a second analyte. Those ions are transferred through a discontinuous sample introduction interface into a first ion trap of a mass spectrometer in a manner in which the discontinuous sample introduction interface remains open during the transferring. The discontinuous sample introduction interface is closed and the ions are sequentially transferred to a second ion trap of the mass spectrometer where they are sequentially analyzed.

    Abstract: The invention generally relates to systems and methods for sample analysis. In certain embodiments, the invention provides systems for analyzing a sample that include an electric source, a vacuum chamber including a conducting member, in which the conducting member is coupled to the electric source, a sample introduction member coupled to the vacuum chamber, and a mass analyzer. The system is configured such that a distal end of the sample introduction member resides within the vacuum chamber and proximate the conducting member, such that an electrical discharge may be produced between the sample introduction member and the conducting member. A neutral gas that has been introduced into the vacuum chamber interacts with the generated discharge, producing ions within the vacuum chamber that are subsequently transferred into the mass analyzer in the vacuum chamber.
