Applications
1. Alternate column regeneration - 10 port 2. Backflush of precolumn to vent - 6 port 3. Detector selection from two columns, or one column and auxiliary carrier - 4 port 4. Dual microvolume sample injection - 6 port 5. Heart cut trapped in a loop and injected onto a second column - 10 port 6. Loop sampling with backflush of precolumn to vent - 10 port 7. Loop sampling with two column sequence reversal - 10 port 8a. Microvolume sample injection - 4 port (Valco and Cheminert valves) 8b. Microvolume sample injection - 4 port (Diaphragm valves) 9. Same sample to different loops - 8 port 10. Sample enrichment (cleanup) using dual precolumns - 10 port 11. Sample injection - 6 port 12. Sample injection and heart cut to detector - 10 port 13. Sample injection, end and heart cut to column 2, front cut to detector - 10 port 14. Simultaneous injection of the same sample onto two separate columns - 10 port 15. Simultaneous injection of the same sample onto three separate columns - 14 port 16. Two column selection - 6 port 17. Two different samples to same column - 10 port 18. Two different samples to two columns - 12 port
