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.
