This chapter describes routine service procedures for the Thermo Scientific
Dionex ICS Series Photodiode Array Detector (Dionex PDA) that users may
perform. All procedures not described here, including electronics-related repair
procedures, must be performed by Thermo Fisher Scientific personnel. For
assistance, contact Technical Support for Dionex products. In the U.S. and
Canada, call 1-800-346-6390. Outside the U.S. and Canada, call the nearest
Thermo Fisher Scientific office.
The Data Processing board contains a lithium battery. If the board is
replaced, dispose of the used battery according to local regulations.
Before replacing any parts, review the troubleshooting information in Chapter 4 to
isolate the cause of the problem.
5.1 Liquid Leaks
The Dionex PDA is plumbed with the parts listed below. For tightening
requirements, refer to
Installation of Dionex Liquid Line Fittings (Document No.
031432). The manual is on the Thermo Scientific Reference Library DVD
(P/N 053891).
Note that the tubing connected to the heat exchangers (standard and semi-micro
cells only), as well as the semi-preparative cell inlet and outlet tubing, cannot be
replaced. If a leak (at the cell inlet, for example) cannot be eliminated by
tightening the fitting, you must replace the entire cell (see
Section 5.6 ).
Substituting non-Dionex/Thermo Scientific parts may impair the
performance of the Dionex PDA, thereby voiding the product
warranty. Refer to the warranty statement in the Dionex Terms and
Conditions for more information.
