Installation of Stainless Steel Cladded PEEK Capillaries

The 1260 Infinity Bio-inert LC system uses PEEK capillaries that are cladded
with stainless steel. These capillaries combine the high pressure stability of
steel with the inertness of PEEK. They are used in the high pressure flow path
after sample introduction (loop/needle seat capillary) through the
thermostatted column compartment/heat exchangers to the column. Such
capillaries need to be installed carefully in order to keep them tight without
damaging them by over-tightening.
The installation consists of two steps. In the first step, the fitting is installed
finger-tight without using tools. Finger-tight means that the fitting will grip
and hold the capillary. This brings the fitting to the appropriate start position
(marked as 0 ° below) for the second step.

First Step: Finger-tight Fitting

1 Tighten the fitting using your fingers.
