ABSTRACT:
An automatic sampling apparatus for particles suspended in liquid, which maintains particles in suspension by periodically directing and redirecting the liquid first down one branch of a manifold and then down another, and which selectively directs the liquid toward one or more of a plurality of filters, engaging in both operations under the direction of a programmable process controller. Liquid flow rate through the filters is metered, providing information regarding flow rate and volume to the process controller. A minimum of manual handling is required and user exposure to the sampling environment, which may be radioactive, is reduced.
