Apparatus for converting a continuous liquid stream to a stream of liquid droplets

摘要

In an apparatus for the conversion of a continuous liquid stream into a stream of liquid droplets, which are discharged from a discharge nozzle of the capillary through which the liquid stream is conducted, a flow acceleration device is disposed on the capillary near the discharge nozzle thereof for accelerating the droplet stream depending on a first electrical signal, which is applied to the acceleration device, and a second electrical signal which is generated by a laser detection means provided for sensing laser light of a beam directed through the travel path of the droplets to the detection means for sensing the passage of a droplet and means for generating from the first and second electrical signals a time Deltat which indicates the time needed for a liquid droplet to travel from the discharge nozzle to the laser light beam.
