9.1 Troubleshooting Strategies
For any system, the initial troubleshooting objective is to isolate the source of the
problem to a specific system component or to an aspect of the analysis. Once this
has been done, corrective action can be taken. This manual cannot address every
possible symptom and failure; however, the techniques discussed here can be
applied to problem solving throughout the Dionex Integral system.
A solid understanding of system operation is necessary for troubleshooting.
Rather than immediately assuming that a problem exists, first check the user
manuals to verify that correct operating procedures are being followed.
Also, it is essential that users keep a log of all maintenance-related activities (for
example, when eluents are prepared and when columns are changed). Tracking
these events can provide valuable insights. For example, if the chromatogram on
an anion system seems to have undergone a radical and sudden change, check the
log or audit trail for the date that the latest batch of eluent was placed in service. If
the problem was first observed with the new batch, verify that the eluent was
properly prepared. Maintaining a written record of problems and their resolution
can help solve similar problems in the future.
