Multisyringe separation system

FIGURE 9.10 Schematic diagram of a multisyringe separation system using solenoid valves rather than a multiposition valve. Normally open and normally closed ports on the solenoid valves are marked with open and closed circles, while the common port is unmarked. System is shown with wash and eluent solutions for Sr determination using a Sr-Resin separation column. 

Another multisyringe FI separation system design has been used in the analysis of stable and radioactive Y, using an extraction-chromatographic material containing HDEHP adsorbed on a C18 support.123 Separated samples were analyzed off-line by ICP-AES and proportional counting. This system used four syringe pumps in parallel.
