Abstract
An extremely dilute mixture of a liquid in a flowing fluid stream is prepared by forming tiny droplets of the liquid and injecting the droplets individually into the flowing stream. The rate at which liquid is added to the flowing stream is determined by the number of droplet forming units that are provided and upon the frequency with which the units are activated, allowing a precise digital control of the concentration of the liquid in the flowing fluid stream.
