9.11 Isolating a Restriction in the Liquid Lines
A restriction in the liquid plumbing will cause excessive system backpressure.
1. Begin pumping eluent through the system (including the columns) at the flow
rate normally used.
2. Work backward through the system, beginning at the flow cell exit. One at a
time, loosen each fitting and observe the pressure. The connection at which
the pressure drops abnormally indicates the point of restriction. If the EluGen
cartridge is the source of the high backpressure, replace the outlet frit as
instructed in the EluGen cartridge manual. The manual is included on the
Dionex Reference Library CD-ROM (P/N 053891).
3. If the restriction has caused such high pressure that the system cannot be
operated, you must work forward through the system, adding parts one at a
time, until an abnormal pressure increase (and hence, the restriction) is found.
9.12 Replacing the EluGen Cartridge
Replace the EluGen cartridge when the cartridge is expended or when it
leaks.
The EluGen cartridge replacement procedure consists of:
• Removing the old EluGen cartridge (see Section 9.12.2)
• Disposing of the old EluGen cartridge (see Section 9.12.3)
• Installing the new EluGen cartridge (see Section 9.12.4)
• Conditioning the new EluGen cartridge (see Section 9.12.5)
The EluGen cartridge contains one of the following: a corrosive base
(KOH, LiOH, or NaOH), a corrosive acid (MSA), or a concentrated
K
