A polymeric dispersant having an affinity with a supercritical fluid is provided, in which a substituent having an affinity with a supercritical fluid is attached to the terminal end of a block copolymer. The polymeric dispersant can disperse a dispersoid to particulate size by lowering surface tension between the dispersoid and the supercritical fluid to promote diffusion of the supercritical fluid into the dispersoid.

A method for determining a first concentration of a first component in an aqueous solution, the surface tension of which is altered by the presence of the first component. The method can include identifying a second concentration of at least one second component in the aqueous solution. The at least one second component can also alter the surface tension of the aqueous solution. The method can further include comparing a plurality of dynamic surface tension measurements of each of a plurality of aqueous test solutions with at least one dynamic surface tension measurement of the aqueous solution to determine the first concentration. The plurality of aqueous test solutions can include the first component at a plurality of concentrations and the at least one second component at the second concentration.
