Method for detecting a change of a population of particles in a solution used in drinking water preparation comprises passing a pulsed laser beam through the solution producing plasma emissions on the particles and further processing
Method for detecting a change of a population of particles in a solution used in drinking water preparation comprises passing a pulsed laser beam through the solution producing plasma emissions on the particles and further processing
Method for detecting a change of a population of particles in a solution comprises passing a pulsed laser beam through the solution producing plasma emissions on the particles, measuring the single plasma emissions with a number of laser pulses using an optical or acoustic detector and recording the changes in energy of the laser pulses as a function of time, in which the changes in population of the particles are detected in the measuring volume. Preferred Features: The particles are fractionated before they are inserted into the measuring volume. Coagulation of the particles in the solution is detected.
