Abstract

A sample handling system provides an evenly-suspended, small volume, bubble-free sample to an analyzer such as a light scattering particle size analyzer. A flow of suspension is forced through an elongate channel below the surface of the liquid in the channel, along a downwardly sloping path, into impact with an end wall, and through an abrupt downward turn. Controlled turbulence created in the flow disperses particles and releases bubbles from the liquid.
