摘要： A buffered suspension includes a surfactant and a solid buffer particulate having a point of zero charge at least 1.2 pH units different that the pH of the buffered suspension. The buffered suspension can be prepared by mixing a stock solution with the solid buffer particulate and titrating. A method of preforming a pH sensitive process includes drawing the buffered suspension from a reservoir, filtering the solid buffer particulate from the buffered suspension, and applying the filtered solution to a sensor.

摘要： A sensor component includes a sensor including a sensor surface and a reaction site in cooperation with the sensor and exposing the sensor surface. The reaction site including a reaction site surface. A surface agent is bound to the reaction site surface or the sensor surface. The surface agent includes a surface active functional group reactive with Bronsted base or Lewis acid functionality on the reaction site surface or the sensor surface and including distal functionality that does not have a donor electron pair.

摘要： A method of preparing reagents includes inserting a cartridge into an instrument. The cartridge includes a plurality of reagent enclosures disposed in a cavity of the cartridge and exposing a port to an exterior of the cartridge. Each reagent enclosure includes a reagent container including a reagent and an internal cavity defining a compressible volume, an opening defined through the reagent container to the internal cavity. The method further includes connecting a plurality of fluid ports to the openings of the plurality of reagent enclosures; applying a solution through the fluid ports to at least partially fill the plurality of reagent enclosures; and cycling a pressure of the cavity, whereby for each of the reagent enclosures, during increasing pressure, the solution enters the internal cavity of the reagent container, combines with the reagent, and compresses the compressible volume, and during decreasing pressure, the compressible volume decreases and the reagent is ejected through the opening.

摘要： A method of recovering a bead support from an emulsion includes supplying an aqueous surfactant solution into a centrifuge tube; supplying a hydrophobic liquid over the surfactant solution in the centrifuge tube, wherein a ratio of the volume of the aqueous surfactant solution to the volume of the hydrophobic liquid is not greater than 0.5; and applying an emulsion over the hydrophobic liquid while centrifuging, the emulsion comprising a dispersed aqueous phase including the bead support, the emulsion breaking and material of the dispersed phase preferentially partitioning to the surfactant solution.
