17. The method of claim 11, wherein said applying comprises applying the sample to said capillary column with said stationary phase comprising an antibody.
18. The method of claim 11, wherein said applying comprises applying the sample to capillary column with said stationary phase comprising an antigen.
19. The method of claim 11, further comprising applying a differential pressure to capillary column to effect said drawing.
20. The method of claim 11, wherein said drawing occurs without applying differential pressure to said capillary column.
21. The method of claim 20, wherein said drawing comprises capillary action induced by said matrix.
22. The method of claim 11, wherein said drawing comprises applying an electrical current across a length of said capillary column.
23. The method of claim 11, wherein said applying the sample comprises applying the sample to said capillary column with said stationary phase comprising at least one of an antibody and an antigen.
