Figure 3-7 Sample Load Pump options
2. Prepare the Sample Load pump to receive the sample.
If the sample mixture will be transferred to the pump,
insert the cartridge onto the pump inlet (Figure 3-7, Left).
Then, fill the cartridge with the mixture.
If you will transfer the sample mixture directly from a container,
attach the tubing to the pump inlet (Figure 3-7,
Right). Place the weighted end into the mixture container.
3. Place the On/Off (I/O) switch in the On position. Adjust the
pump speed using the control knob.
4. When the desired sample volume has been loaded, place
the On/Off (I/O) switch in the Off position.
Note
After use, always pump clean solvent through the Sample Load
Pump to remove sample residue.
Note
Some of the sample mixture will remain in the tubing before the
automated injection valve. In most applications, pump a chase
solution to force the sample mixture through the injection valve. To
do so, repeat steps 2 through 4 using a suitable chase solvent.
