In order to investigate particles in a fluid, a flow cell causes the fluid to flow past a sensor which receives light from a continuous light emission system. When the sensor detects a change in light, a particle detector is triggered, which in turn triggers a pulse generator and hence an intermittent...http://www.google.fr/patents/US5880835?utm_source=gb-gplus-shareBrevet US5880835 - Apparatus for investigating particles in a fluid, and a method of operation thereof
