SEM images of the three capillary columns produced and used in the platform.

(a): The inner polymeric layer of ≈ 0.75 μm (dried with nitrogen gas) of 20 μm ID HEMA-VDM reactor. (b): The 10 μm ID analytical PS-DVB PLOT column, with a ≈ 0.75 μm (dry) layer of polymer on the inside of the capillary. (c): The monolithic structure of the 50 μm PS-DVB solid phase extraction (SPE) column.
