ABSTRACT:
The present invention is related to a technique for storing concentrated eluant, preparing dilute eluant, and reclaiming water used for dilution. The invention uses stored concentrated eluant which is diluted using a sample loop coupled with a dilute eluant reservoir. Water is used for dilution and is reclaimed using a mixed ion exchange bed. The use of concentrated eluant and reclaimable water significantly reduces storage needs.
