Abstract: The invention generally relates to systems and methods for analyzing an extracted sample using an immiscible extraction solvent. In certain embodiments, the invention provides a system for analyzing an analyte in a sample. The system includes an ionization probe and a mass spectrometer. The ionization probe includes a hollow body that optionally includes a distal tip. The hollow body is configured such that there is no substrate within the body and no electrode disposed on a surface of the body. An electrode is at least partially disposed within the hollow body.

Abstract: The invention generally relates to systems for analyzing a sample and methods of use thereof. In certain aspects, the invention provides systems that include an ionization probe and a mass analyzer. The probe includes a hollow body that has a distal tip. The probe also includes a substrate that is at least partially disposed within the body and positioned prior to the distal tip so that sample extracted from the substrate flows into the body prior to exiting the distal tip. The probe also includes an electrode that operably interacts with sample extracted from the substrate.
