A method using a chemical analyzer for removing a component of a liquid sample which may interfere with a test performed on a test assay includes the steps of adding the liquid sample to a sample cup, transferring a volume of the liquid sample to a mixing cup containing an IMAC (Immobilized Metal Affinity Chromatography) resin containing porous beads to form a sample/resin solution in the mixing cup, using a pipette of the chemical analyzer to repeatedly aspirate the sample/resin solution into a disposable pipette tip of the pipette and expelling the sample/resin solution from the pipette tip into the mixing cup to achieve a mixed sample/resin solution in the mixing cup, and allowing the mixed sample/resin solution in the mixing cup to rest undisturbed so that the interfering component of the liquid sample adheres to the porous beads and the beads settle to a bottom portion of the mixing cup, resulting in a refined liquid sample devoid of the interfering component and occupying an upper portion of the mixing cup for later dispensing on the test assay.
