Abstract
Liquid samples are collected simultaneously by intermittent diversion of a stream withdrawn from a body of liquid to be sampled and passed by a diversion locus into a splitting region having multiple outlets. The liquid is prevented from flowing through the outlets during periods of diversion, and upon completion of such period the outlets are opened to pass liquid streams therefrom. This multipleoutlet confining region is embodied in the sample compartment of a diverter chamber, and the valving includes a horizontally movable slide adapted to close off and to open up all the outlets in unison.
