Storing the NGC Instrument

Tip: You can use the System CIP/Storage phase in ChromLab to store the

fluidic lines and system components.

See the NGC Chromatography Systems

and ChromLab Software User Guide

for more information.

To store the NGC

instrument overnight, note the following precautions:

 Thoroughly flush all valves with water to remove buffer salts.

 If the NGC instrument is in a cold environment, keep it powered on to

prevent condensation. If

it is at room temperature, the instrument can be

kept on or turned off.

If the ChromLab computer is located at room temperature, both the computer

and its monitor can be turned off to conserve energy (as long as no run is in

progress).

To store the NGC

instrument long-term, note the following precautions:

 Follow the manufacturer’s instructions to clean and store the columns.

 If you use the column switching valve, ensure that the valve position is set

to Bypass before you perform System CIP/Storage in ChromLab.

 If you do not use the column switching valve, detach the column from the

instrument.

 Run deionized water through the entire system to wash and remove

contaminants from all wetted parts.

 To inhibit bacterial growth, fill the system’s fluid path with either 20%

ethanol or isopropyl alcohol (IPA) when storing it over prolonged periods.
