20 Installation

Connecting the Capillaries

Capillaries connect the detector with the column and guides li-
quids. For the flow cell connectors, we recommend PEEK capil-
laries and PEEK connectors.

Prerequisite The flow cell is inserted.

Screw-type cap fittings and cap fittings are removed.
Procedure Attach the capillaries with screw fitting.
Procedure Process
1. Push the capillary
through the fitting
2. Slide the lock ring
over the tubing. Note
that the tapered end of
the lock ring has to
point to the seal
ring
3. Attach the seal ring
4. Fasten the capillary at
the flow cell
tight.
Next steps Bring the device into operation.

Using PEEK Fittings

PEEK fittings withstand a maximum pressure of 400 bar. Note
the torque of 0.5 Nm.
