What are the storage conditions for Envirogel GPC Cleanup columns? - WKB125207

ENVIRONMENT

• Envirogel
• Gel permeation chromatography (GPC)
• Size exclusion chromatography (SEC)
• Gel filtration chromatography (GFC)
• Column storage

ANSWER

Short-term:
During short-term column storage (storage overnight or a weekend), ensure that columns do not dry out. Leave the system power ON, and reduce the flow rate to the column to 0.5 mL/min. Divert the detector output to waste. Recalibrate the system upon startup.

Long-term:
Follow the long-term shutdown procedure for your GPC system based on the system operator’s guide. Return the column to its box with the end plugs firmly in place. Store the column at room temperature.
