Sample Pump Direct Inject/System Pump Waste
 Directs system pump flow to waste
(W2)
 Directs sample pump flow directly
onto the column to load large
volumes of sample
 Chromatogram x-axis based on
sample pump flow rate
Sample Pump Load Loop/System Pump to Column
 Directs system pump flow directly
onto the column
 Directs sample pump flow into the
loop to load the loop with sample.
Excess sample flows out through
waste port (W1)
 Chromatogram x-axis based on
system pump flow rate
