FIG. 9. — (a) Composite image showing rhodamine dye (red) superimposed on a brightfield image of the mixing injector (blue). Here, water is flowing through the outer capillary. The dark band midway through the image is a centering spacer. (b) Composite images of the mixer's central channel with outer:inner flow rate ratio of 40:1 for rhodamine dye in the central capillary and water (left) or iodide (right) in the outer capillary. The total flow rate is ∼62 μl/min. White horizontal lines indicate time elapsed along the central jet. (c) Same as in (b), but with outer:inner flow rate ratio of 30:1.
