C Plumbing the System
With the exception of the inlet tubing, waste lines, and column, the NGC™ systems
ship preassembled and preplumbed with the modules necessary to perform
gradient separations. The inlet and waste lines should be plumbed during the
installation process.
However, as your needs change, you can reconfigure your NGC system by inserting
and removing modules. After you reconfigure your system, you will have to replumb
the modules.
