Valve Position Explanation
Manual Load Loop/System Pump to Column
 Directs system pump flow directly
toward the column
 Aligns the sample loop with manual
injection port so that sample can
be manually filled into the loop
using a syringe. Excess sample
goes out waste port (W1)
 Chromatogram x-axis based on
system pump flow rate
System Pump Inject Loop/Sample Pump Waste
 Directs system pump flow through
the sample loop to load the sample
from the loop onto the column
 Directs sample pump flow to waste
(W2)
 Chromatogram x-axis based on
system pump flow rate
