Abstract: Aspects of the present disclosure include a solid phase sorbent for preparation of analytical samples. The solid phase sorbent includes particles that are surface modified with an ?-cyclodextrin moiety. Also provided is a method of reducing matrix effects in an analytical sample. In some embodiments, the method includes contacting a sample comprising a matrix-interfering agent and an analyte with ?-cyclodextrin modified particles to produce a contacted sample wherein the matrix-interfering agent binds to the ?-cyclodextrin modified particles; separating the ?-cyclodextrin modified particles from the contacted sample to produce a matrix-reduced composition; and detecting the analyte in the matrix-reduced composition. Systems for practicing the subject methods are provided that include the subject solid phase sorbent.
