An article that includes a functionalized copolymer and the use thereof, particularly in a process for binding biomaterials, such as in a process for separating aggregated proteins from monomeric proteins in a biological solution; wherein the article includes: a) a porous substrate; and b) a copolymer covalently attached to the porous substrate, the copolymer comprising a hydrocarbon backbone and a plurality of pendant groups attached to the hydrocarbon backbone, wherein 1) each of a first plurality of pendant groups comprises: (a) at least one acidic group or salt thereof; and (b) a spacer group that directly links the at least one acidic group or salt thereof to the hydrocarbon backbone by a chain of at least 6 catenated atoms; and 2) each of a second plurality of pendant groups comprises: (a) at least one acidic group or salt thereof; and (b) a spacer group that directly links the at least one acidic group or salt thereof to the hydrocarbon backbone by a chain of at least 6 catenated atoms; and wherein the first plurality of pendant groups are different than the second plurality of pendant groups; and wherein a mole ratio of the first plurality of pendant groups to the second plurality of pendant groups is in a range of 95:5 to 5:95.

carbonyls investigated. For all but five of the carbonyls examined, a pseudomolecular (M + H)+ ion is the base peak in the APCI positive ion mass spectra of PFBHA oxime derivatives and is observed in four of the five exceptions. Application of the evaluated analysis methodology to heavy-duty diesel source emissions facilitated the quantification of 10aliphatic carbonyls (5 C5-C9 ketones, 4 C6 unsaturated

A process for separating aggregated proteins from monomeric proteins in a biological solution, the process including: providing at least one filter element having a contacting surface, wherein the filter element comprises filter media comprising: a porous substrate; and disposed on the porous substrate, a polymer comprising a hydrocarbon backbone and a plurality of pendant groups attached to the hydrocarbon backbone, wherein each of a first plurality of pendant groups comprises: (1) at least one acidic group or salt thereof; and (2) a spacer group that directly links the at least one acidic group or salt thereof to the hydrocarbon backbone by a chain of at least 6 catenated atoms; and allowing an initial biological solution to contact the contacting surface of the filter element under conditions effective to separate the aggregated proteins from the monomeric proteins such that a final biological solution includes purified monomeric proteins.
