A schematic of the multiport cell that allows for simultaneous measurement of scattered light intensity at 90° and protein concentration through UV detection. Various ports linked to the cell are as follows: (a), main cell encasing; (b), UV source; (c), sample inlet; (d), sample outlet; (e), laser source for light scattering; (f), UV detector; (g), 90° light scattering detector; and (h), 15° light scattering detector.
