FAQ
Why should I have REGULAR, PLANNED MAINTENANCE on my system?
With the pressure on producing sample or results, the condition of your ÄKTAdesign or Ettan system is critical and regular servicing will mean you can depend on your system to perform as expected. Planned maintenance can be part of a service agreement, scheduled to service your system before it is in need of attention. We can help you design a schedule and routine to allow you to maintain your system, please contact your local Cytiva service representative.
So what can you expect from a planned maintenance visit from Cytiva service representative?
- Thorough inspection and cleaning of system components
- Update of system firmware to ensure full compatibility of your system and UNICORN software
- Replacement of damaged or corroded seals, valve springs and solenoids
- Replacement of items that are reaching the end of their expected life – preventing future breakdowns
- Advice and guidance on proper daily use, cleaning and care of your system
- All work is documented and reported to help make any regulatory audits easier.
A complete overhaul, once a year, ensures that your instrument is running at peak performance so you can be confident of your scientific results. In addition, wear and tear on systems under constant use by multiple end users is minimized, giving the system a longer life and better value for money.

Purifying some samples at room temperature can lead to increased levels of degradation; performing your purifications at 4C can help. All our ÄKTA systems, Ettan LC, Ettan microLC, Ettan nanoLC and fraction collectors are suitable for use in the temperature range of 4-40C.
The computer systems are not however cold room compatible, and can be damaged by being placed at 4C.
When installing an ÄKTA system in a cold room the computer can be positioned up to 15 m away, allowing it to be positioned outside the cold room. Cold cabinets can provide an effective solution to running your ÂKTA system in the cold whilst protecting the PC. When moving a system to or from a cold room, time must be allowed for the system to adjust to its new temperature. You may also find that you need to tighten the connectors on your system slightly to prevent leaks when you bring a system out from the cold, and loosen them slightly before you put a system into the cold to prevent pressure build up.
Changes in temperature can also affect the viscosity of your buffers so keep a close eye on your back pressure.
This section specifies the chemical resistance of ÄKTA pure to some of the most commonly used chemicals in liquid chromatography.
Assumptions made
The ratings are based on the following assumptions:
- Synergy effects of chemical mixtures have not been taken into account.
- Room temperature and limited overpressure is assumed.
Chemical influences are time and pressure dependent. Unless otherwise stated, all concentrations are 100%.
List of chemicals
Proposed chemical compatibility for ÄKTA pure. All chemicals used for CIP and cleaning are for short term use only, ambient temperature < 25ºC, if not other stated.
Note: A user can be exposed to large volumes of chemical substances over a long time period. A Material Safety Data Sheet (MSDS) provides the user with information regarding characteristics, human and environmental risks and preventive measures. Make sure that you have the MSDS available from your chemical distributor and/or databases on the internet.

1 PEEK tubing is biocompatible and chemically inert to most solvents used in the purification of proteins. It has in general very good pressure limits, especially for water based buffers. However, organic solvents can penetrate weaknesses in the tubing walls more easily than water based buffers. Special care should therefore be taken with prolonged use of organic solvents close to pressure limits.
2 If hydrochloric acid, HCl, is used as a cleaning agent when columns are connected to the system, the HCl concentration should not exceed 0.1 M in the System pressure monitor or in the pressure monitor in Column valve V9-C.
For other parts of the system up to 1 M HCl is acceptable for short time use.
For cleaning of columns with HCl concentrations exceeding 0.1 M, manually fill a loop with HCl and inject the cleaning agent.

Location of the I/O box
The illustration below shows the I/O-box and its recommended location and connection points.
Function of the I/O-box
The I/O-box E9 is used to interface other equipment in order to measure parameters such as refractive index, light scattering and fluorescence. See Requirements on connected equipment, on page 196 for information on requirements of the equipment that can be connected to ÄKTA pure. The I/O-box can control external equipment by a digital output signal, as well as detecting the state of them by digital inputs. It is possible to install up to two I/O-box E9 when using ÄKTA pure. If two I/O-boxes are to be used, the second one has to be configured as I/O-box E9, 2nd. The configuration is defined by the I/O-box E9 Node ID.

Up to four external air sensors can be added to ÄKTA pure, and there are two different versions to choose from. They differ in internal diameter and optimal position on the instrument.
The air sensors can be attached to the instrument using the rails and holders. No dummy modules need to be removed.
In addition to be used for preventing air from entering the system, the external air sensors can be used together with System pump A to load the entire sample volume.
Air sensor L9-1.5
L9-1.5 has a 1.5 mm inner diameter and is designed for i.d. 1.6 mm FEP tubing at the low pressure side before pumps. It is installed in the flow path before the system pumps and is used to prevent air entering the valve.
Air sensor L9-1.2
L9-1.2 has a 1.2 mm inner diameter and is designed for o.d. 1/16" tubing at the high pressure side after the pumps. It is installed after the injection valve and is used to prevent air entering the column.

Select Mixer chamber
To obtain a homogeneous buffer composition, it is important to use a Mixer chamber suitable for the flow rate of the method. The tables below show what Mixer chambers to use in ÄKTA pure at different flow rates.
If the liquids are difficult to mix, use a larger Mixer chamber to achieve optimal mixing. However, note that a larger Mixer chamber distorts and delays the gradient.
Three different Mixer chambers are available for ÄKTA pure 25. Their volumes are: 0.6 ml, 1.4 ml (mounted at delivery), and 5 ml.
Mixer chamber volume [ml] | Flow rate [ml/min], Binary gradient |
---|---|
0.6 | 0.1-5 |
1.4 | 0.5-10 |
5 | 5-25 |
CAUTION
Risk of explosion. Do not use Mixer chamber 15 ml with an ÄKTA pure 25 configuration.
The maximum pressure for Mixer chamber 15 ml is 5 MPa.
Four different Mixer chambers are available for ÄKTA pure 150. Their volumes are: 0.6 ml, 1.4 ml
(mounted at delivery), 5 ml (included in delivery), and 15 ml.
Mixer chamber volume [ml] | Flow rate [ml/min], Binary gradient |
---|---|
0.6 | 0.5-5 |
1.4 | 0.5-15 |
5 | 2-50 |
15 | 15-150 |
Note: At low flow rates (below 0.2 ml/min) a gradient of sufficient quality may be achieved with the mixer bypassed.
Note: For the highest flow rates, use the 5 ml mixer for ÄKTA pure 25 and the 15 ml mixer for ÄKTA pure 150. The larger chamber volume minimizes potential pump disturbances.
Note: The 1.4 ml mixer might work up to 25 ml/min provided that the buffers are easily mixed.
Note: O-ring 13.1 x 1.6 mm 28-9535-45 is for use with Mixer chamber 0.6, 1.4 and 5 ml.
Note: O-ring 22.1 x 1.6 mm 28-9818-57 is for use with Mixer chamber 15 ml.
Note: O-ring 13.1 x 1.6 mm 29-0113-26 (high resistant) can be used as an alternative to 29-9535-45.

Function of UV monitor U9-L
The UV monitor U9-L measures the UV absorbance at the fixed wavelength of 280 nm. It is not possible to vary the wavelength, or turn on or off the U9-L monitor. This is therefore not shown in the Phase Properties pane in Method Editor.
For information on how to install UV monitor U9-L, please refer to Section 4.10 Install UV monitor U9-L, in the system handbook.
Function of UV monitor U9-T
The UV monitor U9-T measures the UV absorbance at the fixed wavelengths of 260 and 280 nm. It is not possible to vary the wavelength or turn on or off the U9-T monitor on and off. This is therefore not shown in the Phase Properties pane in Method Editor.
For information on how to install UV monitor U9-T, please refer to Section 4.10 Install UV monitor U9-T, in the system handbook.
Using two UV monitors
The UV monitor U9-T module has two configurations: UV monitor U9-T and UV monitor U9-T, 2nd. The configuration is defined by the module's Node ID. It is possible to use two UV monitors for ÄKTA pure™ in the following combinations:
• UV monitor U9-M together with UV monitor U9-L and or U9-T, 2nd
• UV monitor U9-L together with UV monitor U9-L, 2nd
UV monitor U9-T, 2nd can be located anywhere in the flow path and is therefore shown in the Process Picture as a component without a fixed place. This means that it is possible to place U9-T, 2nd before the other UV monitor in the flow path.
Note: If U9-T, 2nd is placed on the high-pressure side of the column, pressure limits have tomust be considered.

Tubing with a smaller inner diameter (i.d.) holds less delay volume and will therefore generate less dilution of the protein peak. Narrow tubing, however, increases the system pressure, especially when running at high flow rates. The tubing used should match the application needs. See Recommended tubing kits, on page 467 in the System Handbook for more information.
