A4.2 - A Continuous Flow Multi-Laminar Micromixer with Improved Flow Profile for Infrared Analysis of Chemical Reaction Kinetics

W. Buchegger, M. Vellekoop, Ch. Wagner, B. Lendl & M. Kraft
The use of micromixers in infrared (IR) spectroscopy is promising e.g. for the study of biomolecular kinetics. To prevent excessive IR absorption by the medium, a maximum channel height of 8 μm was applied in this mixer. An new design generates four laminated fluid layers out of two fluid feeds by a distribution network. Using a 2D simulation the fluid layers are optimized in their thickness to reduce the mixing time by a factor of...
