3 Installing the Module

Get the System Ready for the First Injection

When you are using the system for the first time it is recommended to prime it

to remove all the air and the possible contamination introduced in the flow

path during the installation.

Manually Priming the Solvent Channels

1 The degasser accessory kit contains a 20 mL plastic syringe and a solvent

tube adapter for the syringe. Push the adapter onto the syringe.

2 Fill required analytical solvents into the solvent bottles, and install the

bottles on the described solvent channels. Use isopropanol for channels

which will not be used right away.

3 Put a paper towel over the leak sensor in the pump leak tray.

4 Disconnect the channel A solvent tube from the A1 port of the pump solvent

selection valve.

5 Connect the end of the solvent tube to the syringe adapter. Slowly draw one

syringe volume (20 mL) from the solvent tube.

6 Disconnect the solvent tube from the syringe adapter, and reconnect the

tube to the A1 port of the solvent selection valve. Eject the syringe contents

into an appropriate waste container.

NOTE

The pump should never be used for priming empty tubings (never let the pump run dry). Use

the syringe to draw enough solvent for completely filling the tubings to the pump inlet

before continuing to prime with the pump.

WARNING

Liquid may drip from the disconnected solvent tube.

➔ Make sure to follow appropriate safety precautions.

NOTE

This procedure should be carried out before the modules are turned on.
