Abstract
MS-based methods and systems are provided herein in which a desorption solvent desorbs one or more analyte species from an SPME device within a sampling interface that is fluidly coupled to an ion source for subsequent mass spectrometric analysis. In accordance with various aspects of the applicants teachings, the sampling interface includes an internal sampling conduit that provides increased interaction between the desorption solvent and the sampling substrate, thereby improving mass transfer (e.g., increased extraction or desorption speed).
