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