	abstract = {The direct interface of microextraction technologies to Mass Spectrometry (MS) has unquestionably revolutionized the speed and efficacy at which complex matrices are analyzed. Solid Phase Micro Extraction-Transmission Mode (SPME-TM) is a technology conceived as an effective synergy between sample preparation and ambient ionization. Succinctly, the device consists of a mesh coated with polymeric particles that extract analytes of interest present in a given sample matrix. This coated-mesh acts as a transmission mode substrate for Direct Analysis in Real Time (DART), allowing for rapid and efficient thermal-desorption/ionization of analytes previously concentrated on the coating, and dramatically lowering limits of detection attained by sole DART analysis. In this study, we present SPME-TM as a novel tool for the ultrafast enrichment of pesticides present in food and environmental matrices and their quantitative determination by MS via DART ionization. Limits of quantitation in the sub-nanogram per milliliter range can be attained, while total analysis time does not exceed 2 minutes per sample. In addition to target information obtained via tandem MS, retrospective studies of the same sample via high-resolution MS (HRMS) were accomplished by thermally desorbing a different segment of the microextraction device.},
