Research output: Contribution to journalArticlepeer-review


A microflow apparatus has been built with a time resolution of 1 ms for mixing volumes of at least 80 μl per syringe. A time resolution of 3 ms is attained for mixing volumes of 10 μl per syringe. Equal volumes are mixed and concentration changes are observed photometrically using fiber optics for coupling light into and out of the observation tube having 1 mm diameter and 10 mm light path length. The reaction of ferrocytochrome c with ferrihexacyanide was used to calibrate the apparatus at 550 nm (10 nm half-width).
