Patent ID: 8173441

Claim:
An NMR apparatus comprising an NMR probe suitable for flow-through NMR screening of a test sample, wherein said apparatus comprises a probe; wherein said probe comprises a first vessel and a second vessel; wherein the first vessel and second vessel are connected to a flow inlet and a flow outlet, wherein both vessels contain a solid support; wherein the solid support comprises a polymer, wherein only one of said solid supports has a target immobilized thereto; wherein said target is reusable in situ; wherein said probe comprises only one detection coil which is arranged around said first and second vessels; and wherein the apparatus comprises a first means for generating a pulsed-radio field which at least extends into the first and second vessels of the sample holder, and wherein the apparatus comprises a second means consisting of one or more gradient coils suitably arranged to deliver a pulsed radio field with a linear amplitude gradient along a transverse axis to the first and second vessels.
