3 Put the alignment interface on the insertion tool and press down firmly. 
Press only on the outer ring to release the spring that secures the capillary 
in the alignment interface.

4 Slide the capillary through the opening in the direction of the arrow printed 
on the interface.
5 The capillary has a plastic stop fitted. Pull the capillary through the 
alignment interface until the stop is reached.
6 While still slightly pulling the capillary, stop against the alignment 
interface, and release the alignment interface from the installation tool to 
secure the capillary in the alignment interface.
The detection window or the extended light path of the capillary must be 
visible through the detection interface. If aligned correctly, you can see the 
slit of the interface behind the detection window. See Figure 30 on 
page 127.
Four plastic pins in the alignment interface belong to a feather-driven mechanism to fix the 
capillary tight in an optimal position for the light path. Press these pins with the alignment 
tool when inserting a capillary. Insertion attempts of capillaries without this can damage 
capillary ends and may lead to dissatisfying results.
