Figure 2
This fluorescence experiment illustrates the mixing process. The field of view shows only the innermost capillary tube at the `Mixing Region' indicated in Fig. 1. (a) Fluorescent dye in the inner line, water in the outer line. (b) Fluorescent dye in the inner line, quencher in the outer line. Quenching represents the mixing process. A blue background is seen along the lower edge of each image. |
