Introduction to the Agilent 7100 Capillary Electrophoresis System

5 Using the Agilent 7100 Capillary Electrophoresis System

Installing a Capillary in the Alignment Interface
The following procedure describes how to install a capillary into an alignment
interface. A capillary must have an alignment interface installed before it can
be installed into the capillary cassette in order to align the inner capillary
with the light path of the diode array detector
Material Needed to Install a Capillary in the Alignment Interface
• Capillary
• Corresponding alignment interface
• Capillary insertion tool (separate item) or part incorporated in cassette
• Safety glasses
WARNING
Risk of injury of sharp capillary ends.
Sharp capillary ends can injure your eyes or skin.
• Wear safety glasses when opening the cassette and handling the capillary to
protect your eyes and body.
NOTE
Alignment interfaces for the 7100 CE instrument differ from alignment interfaces for earlier
instruments. Interfaces from earlier instruments do not fit into the diode array detector
block.
Color Coding of Capillaries and Alignment Interfaces
The alignment interface must correspond to the type of capillary used. There
are special alignment interfaces for straight capillaries and for extended light
path capillaries. The alignment interface must also correspond to the inner
diameter of the capillary. To make it easier to match the capillary and
corresponding alignment interface, we use the following color coding on both
the sleeve of the alignment interface and the plastic stop on the capillary.
