1. An apparatus for detecting the solute burden of an effluent of a liquid chromatograph column comprising:

  • means for emitting an effluent liquid stream from the chromatograph column, in the form of spherical droplets, through an opening in the liquid chromatograph column at a constant velocity and over a common path, each of said droplets being imparted with an electric charge due to the spray electrification effect occurring on each droplet as each droplet is emitted from the liquid chromatograph column, the amount of said electric charge acquired by each droplet being dependent upon the nature and quantity of the solute carried by said droplet;

    means for altering the path over which each of said droplets travels as a function of said electric charge acquired by each droplet;

    means for recording the solute burden of each droplet in said series of droplets as a function of the deviation of the droplets from said common path.
