After run procedures
Introduction
This section describes how to clean the instrument and columns after a chromatographic run, and
how to prepare the system for storage.
The instrument and the columns should be cleaned between the runs. This will prevent, for example,
sample contamination, protein precipitation and column clogging. If the instrument is not going to be
used for a couple of days or longer, the instrument, columns and the pH flow cell should be filled with
storage solution. For further information about cleaning and maintenance procedures, see Chapter 7
Maintenance, on page 252.
To clean and fill the instrument and columns with storage solution, use System CIP and Column
CIP either as separate, predefined methods or as phases included in a chromatographic
method.
Tip:
CAUTION
Hazardous chemicals and biological agents. Before maintenance, service and
decommissioning, wash the ÄKTA pure instrument with a neutral solution to make
sure that any hazardous solvents and biological agents have been flushed out from
the system.
System cleaning
After a method run is completed, perform the following:
• Rinse the instrument with one or several cleaning solution(s) (e.g., NaOH, buffer solution or distilled
water) using System CIP.
If Column valve V9-C or V9H-C is mounted, the integrated pressure sensor of the valve allows
the system to monitor the post-column pressure. The limit for the pressure sensor in Column
valve V9-C or V9H-C is automatically set so that the UV monitor and the pH monitor are
protected from high pressure. If Column valve V9-C or V9H-C is not mounted, make sure
to keep the pressure in the system after the column below the pressure limits for the modules
in the flow path.
Note:
• If applicable, empty the fraction collector.
• Clean all spills on the instrument and on the bench using a moist tissue.
• Empty the waste vessel.
• Clean the manual injection port of the injection valve, see Section 7.6.2 Perform System CIP, on
page 278 for detailed instructions.
• If applicable, clean the pH electrode manually and make sure to leave it in an appropriate buffer.
See Section 7.6.7 Clean the pH electrode, on page 293 for detailed instructions.
