Abstract
This invention is directed to a hydraulic multiplex unit for receiving continuously one or more samples of liquid from a liquid purification system of distribution system and redirecting such sample or samples randomly or in sequence to one or more analytical instruments. The sample collecting system and multiplex unit is periodically backflushed with ozone to maintain the collection and analysis system clean of impurities, particles and the like which adversely affect the composition of the fluid samples.
Claims23
A method of continuously sampling one or more points in a fluid purification system and/or in a distribution system loop for using the purified fluid and analyzing each sample for one or more characterizations comprising continuously feeding each sample stream to a multiplex unit and manipulating said multiplex unit to direct each continuous sample stream to the desired analytical instrument for analysis, or to a drain or recycled to the fluid purification system.
In the fluid purification system and distribution system loop of the purified fluid, the improvement comprising means for continuously obtaining fluid samples at one or more selected points in said purification and distribution systems and feeding said samples continuously to a multiplexer unit containing a valve system which is capable of being manipulated to direct the fluid samples to one or more analytical instruments for measuring a characteristic of said fluid samples or to a drain or recycled to the fluid purification system.
