Abstract: A sampling device is disclosed, including a substrate, a reservoir surface disposed on at least a portion of the substrate and configured to retain a liquid, the reservoir surface having a reservoir surface area and being formed of a reservoir surface material, and a Taylor cone emitter portion. The reservoir surface is essentially impermeable. The reservoir surface is essentially non-porous. The sampling device has a decreased loading time to target analyte saturation relative to an otherwise identical comparative sampling device having at least one of a permeable reservoir surface or a porous reservoir surface.

Abstract: A Taylor cone emitter device repository is disclosed including a repository plate, a repository wall extending therefrom, and an array of orifices and an array of clocking feature interfaces disposed therein. The array of orifices receives and retains an array of Taylor cone emitter devices. The array of clocking feature interfaces guide clocking features of the array of Taylor cone emitter devices into predetermined radial orientations. The repository wall peripherally surrounds a substrate chamber configured to receive a microtiter array tray with the array of solid phase microextraction devices each disposed within a separate well of the microtiter array tray. A Taylor cone emitter device repository system is disclosed including the microtiter array tray, the array of Taylor cone emitter devices, and the Taylor cone emitter device repository system. A method for analyzing a population of samples with the Taylor cone emitter device repository system is disclosed.
