Multicolumn Selection
Advantages
•Increase productivity
•Higher instrument up- time
Quickly change between up to eight different stationary phases for different
applications, or use 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.

Install the Valve Heads
Remove the Transportation Lock and the Valve Dummy
Install the Valve Heads
The valve drives are factory- installed in the 1290 Infinity II 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 5.
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.
1When unscrewing the transportation lock, push it back until the
last screw is removed - the valve rail is spring-loaded.
2Press on the valve dummy to release it (spring-loaded valve
rail).

Remove the Transportation Lock and the Valve Dummy
NOTE
Following procedures may show the 1290 Infinity TCC. The MCT uses the same valve heads, the
valve head installation is the same.
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 6.

The valve actuator contains sensitive optical parts, which need to be protected from dust and
other pollutions. 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.
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.
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
CAUTION
CAUTION
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.

Install the Valve Head and Connect Capillaries
1Insert the valve head into the valve shaft.
OR
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 continue turning the valve head until the pin fits into
the groove.
2When the outer pin is locked into the groove, manually screw
the nut onto the valve head.
NOTE
Fasten the nut manually. Do not use any tools.

3Install all required capillary connections to the valve. 4Push the valve head until it snaps in and stays in the rear
position.
5Power on or power-cycle your module, so the valve head gets recognized during module initialization.
Damage to the rotor seal
Instant pressure release within the valve will lead to water jet effects that can harm internal
parts of the valve. This pressure release typically happens if the valve gets switched under high
pressure over unused or open channels.
➔Block all unused channels properly with the M4 blank nut.
CAUTION
NOTE
To minimize valve movement over open connections it is recommended to plumb the column
connected channels in one row.
e.g.:
•channel 1 – column 1
•channel 2 – column 2
•channel 3 – column 3
•channel 4 – column 4
•channel 5 – blocked
•channel 6 – blocked
•channel 7 – waste
•channel 8 – bypass
NOTE
The blank nuts are only required for the ports on the inner circle that connect the valve with the
column inlet.
