Fluorescence bead spectroscopy uses a pair of fibers configured at right angles. The beads are held in place by the vertical optical fiber. For details see slide 3.3.14.
Simultaneous UV-VIS Spectrophotometry and fluorescence uses three optical fibers configured as shown on the right. The vertical optical fiber retains beads in place. See slide 3.3.14.
Microcolumn chromatography on a renewable column. The flow cell optical path is defined by the distance between optical fibers. The bead column is retained by one of the optical fibers. For details see section on Affinity Chromatography 3.4.1.
BIS combined with microcolumn chromatography uses two pairs of optical fibers. The upper pair monitoring the column, the lower pair monitoring the flow cell. The bead column is held in place by an optical fiber. See Section 3.4.12.
