The Tomographical Dual Wavelength Photometry—A New Tool to Distinguish Micro-and Macro-Mixingside stirred vessels. This is done by injecting a mixture of an inert and a reacting dye into the vessel. The inert dye serves as a tracer for the macromixing, whereas the vanishing of the reacting dye shows the micromixing.
