    Abstract: 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.

    Abstract: 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.
