Abstract: A dispense system stores a scented material or materials and is provided with an electrical interface that is compatible with a hand-held device. The dispense system can be connected to the hand-held device and driven with the help of the hand-held device to dispense the scented material. The dispense system can be configured to store different scented materials that can be mixed to create different scents. Logic within the hand-held device supports the mixing and dispensing of the scented materials.

Abstract: A microanalytical device is provided for conducting multiple chemical and/or biochemical reactions and analyzing multiple sample fluids in parallel using minute volumes of reaction or sample fluid. The devices comprises a well plate with an integrated microfluidic system containing processing compartments such as microcavities, microchannels and the like, that are in fluid communication with electrospray emitters. The novel microanalytical device can be used in a variety of chemical and biochemical contexts, including mass spectroscopy, chromatographic, electrophoretic and electrochromatographic separations, screening and diagnostics, and chemical and biochemical synthesis. The devices may be formed from a material that is thermally and chemically stable and resistant to biofouling, significantly reducing electroosmotic flow and unwanted adsorption of solute.

Abstract: The invention relates to a device for transporting sample fluids into a mass spectrometer. The device comprises a well plate comprising a plurality of wells, a fluid transporting assembly, and a mass spectrometer interface. The fluid-transporting assembly is comprised of a plurality of fluid-transporting conduits, each extending from an inlet port to an outlet port, wherein the assembly exhibits sufficient flexibility to allow movable positioning of the outlet ports with respect to the inlet ports. Each inlet port of the fluid-transporting assembly is positioned in fluid communication with a different well of the well plate to form a plurality of flow paths. Each flow path originates at a well and travels, in succession, through the conduit inlet port, the conduit, the conduit outlet port, and the mass spectrometer interface. Fluids emerging from the mass spectrometer interface may be introduced into a mass spectrometer.
