Abstract: A collection device is disclosed having a tubular housing detachably receiving a valved bulb reservoir at a first end thereof, the housing having a second end for dispensing fluids. The valved bulb reservoir has a sample capillary tube attached at one end thereof. The bore of the capillary is fluidically coupled to the valved bulb reservoir. The capillary is removed from the tubular housing to collect a sample in its bore, and is then replaced into the tubular housing. The contents of the valved tubular reservoir, which can be a buffer solution, a reagent, or other analytic fluid, or a gas, are then passed through the capillary bore to expel the sample and mix therewith in the housing. The sample product can then be dispensed from the tubular housing.

Abstract: A method and system for solid phase extraction of a compound of interest from a sample matrix using a syringe having a barrel and a plunger, a sorbent for use with the syringe, and a desalting purification column having an end configured to receive liquid from the syringe body.

Abstract: A magnetic mixing device designed to mix fluid in a reaction chamber and remove air bubbles if present. The device comprises a holder with embedded magnets, which causes movement of a stir bar within the reaction chamber. The holder may be moved by an electric linear actuator configured to generate linear motion or an electric motor configured to generate a circular motion. When orientated so the stir bar moves vertically within the reaction chamber, the stir bar disrupts any air bubbles trapped within or below the fluid.
