Typical Applications

Multicolumn Selection

Advantages

•Increase productivity

•Higher instrument up-time

The valve facilitating quick changes allows the selection between up to four

different stationary phases for a variety of applications, or the usage of

identical stationary phases in columns with different dimensions for either

faster run-times (short columns) or higher resolution (long columns) or for

loading studies with different internal diameters.

Advantages:

•Faster method development

•Automated method development possible

Install the Valve Heads

The valve drives are factory-installed in the Multicolumn Thermostat. The

valve heads are interchangeable and can be easily mounted.

At the first installation, the transportation lock and the dummy valve have to

be removed, see “Remove the Transportation Lock and the Valve Dummy” on

page 6. The valve heads can be installed by mounting the valve heads onto the

valve drives and fastening the nut manually (do not use any tools).

Be sure that the guide pin snaps into the groove of the valve drive thread.

Remove the Transportation Lock and the Valve Dummy

The following procedure demonstrates the necessary steps for installing the

valve head to the valve drive of a Multicolumn Thermostat (MCT).

For the installation of a valve head to a G1170A Valve Drive you can ignore the

steps that describe the MCT features of the transportation lock and spring

loaded valve drive.

1Switch off the module.

2When unscrewing the transportation lock, push it back until the last screw

is removed - the valve rail is spring-loaded.

NOTE

The valves are mounted on pull-out rails to allow easy installation of

capillaries. Push the valve gently into its housing until it snaps into

the inner position, push it again and it slides out.

When all capillaries are installed, push the valve back into its

housing, see “Install the Valve Head and Connect Capillaries” on

page 8.

3Press on the valve dummy (1.) to release it (2.) (spring-loaded valve rail).

Install the Valve Head and Connect Capillaries

For bio-inert modules use bio-inert parts only!

CAUTION

The valve actuator contains sensitive optical parts, which need to

be protected from dust and other pollution. Pollution of these

parts can impair the accurate selection of valve ports and

therefore bias measurement results.

➔Always install a valve head for operation and storage. For

protecting the actuator, a dummy valve head can be used

instead of a functional valve. Do not touch parts inside the

actuator.

CAUTION

Column Damage or Bias Measurement Results

Switching the valve to a wrong position can damage the column

or bias measurement results.

➔Fit the lobe to the groove to make sure the valve is switched to

the correct position.

CAUTION

Valve Damage

Using a low pressure valve on the high pressure side can damage

the valve.

➔When using multiple column compartments as part of a

method development solution, make sure that the high

pressure valve head is connected to the autosampler and the

low pressure valve head is connected to the detector.

CAUTION

Sample degradation and contamination of the instrument

Metal parts in the flow path can interact with the bio-molecules

in the sample leading to sample degradation and contamination.

➔For bio-inert applications, always use dedicated bio-inert parts,

which can be identified by the bio-inert symbol or other

markers described in this manual.

➔Do not mix bio-inert and non-inert modules or parts in a

bio-inert system.

CAUTION

Wrong combination of fitting with valve

The InfinityLab Quick Turn fitting (5067-5966) is not compatible

with the G5639A Bio-inert 4-Column Selector Valve. Misuse can

lead to extra dead volume and leaks.

➔As fitting, use UHP fitting (5067-5403) instead.

NOTE

For information about the compatibility mode of 800 bar valve heads

see Information on RFID Tag Technical Note (01200-90134).

NOTE

For a correct installation of the valve head, the outside pin (red) must

completely fit into the outside groove on the valve drive’s shaft (red).

A correct installation is only possible if the two pins (green and blue)

on the valve head fit into their corresponding grooves on the valve

drive’s actuator axis. Their match depends on the diameter of the pin

and groove.

NOTE

The tag reader reads the valve head properties from the valve head

RFID tag during initialization of the module. Valve properties will not

be updated, if the valve head is replaced while the module is on.

Selection of valve port positions can fail, if the instrument does not

know the properties of the installed valve.

NOTE

To allow correct valve identification, power off the valve drive for at

least 10 s.

NOTE

For firmware requirements see Information on new RFID Tag

Assembly Version Technical Note (01200-90133) which is included to

each valve head.

The following procedure shows the valve head installation with an

G7116A/B (MCT) module as an example. For other modules it is similar.

1Insert the valve head into the valve shaft.

If the outside pin does not fit into the outside groove, you have to turn the

valve head until you feel that the two pins snap into the grooves. Now you

should feel additional resistance from the valve drive while continuously

turning the valve head until the pin fits into the groove.
