Abstract

Apparatus for performing analysis of a slurry including solid particles of elements in a liquid suspension has a container for receiving a sample of the slurry to be analyzed, and a conveyor for moving the container to a location at which the analysis is to be performed. A sampling probe is to be introduced into the slurry sample to perform the analysis. A separate probe is adapted to ultrasonically agitate the slurry sample to keep the solid particles in suspension. The agitating probe is automatically introduced into and withdrawn from the container in synchronism with the movement of the container into the desired location and immediately prior to the introduction of the sampling probe into the slurry sample.
