3.5.3 Starting and Stopping Flow Delivery
When the desired parameters have been entered, the flow delivery can be started
with the START/STOP key (item 2, FIGURE 3-5). This key is also used to stop
the flow delivery.
3.5.4 Purging the Loading Pump
To purge the loading pump, opening the purge valve and then press the PURGE
key on the pump (item 1, FIGURE 3-5). To assure proper purging of the solvent
lines, set the flow rate to 0.5 mL/min. Select each of the four solvent bottles A,
B, C and D by the SSV button on the rear panel. Each of the four solvent
channels should be flushed for approximately 2 minutes and the operator should
ensure that no air bubbles are observed in the mobile phase.
CAUTION
Caution: Purging the system without opening the purge valve knob may cause
damage to your column and/or the system.
