Shutting Down The Detector - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

5.9 Shutting Down the Detector

Observe the following precautions before interrupting the operation or before shipping the
detector:
• Even during periods of detector inactivity, a flow cell or the cover shipped with the
detector must be installed. This is to prevent dust particles from causing damage to the
detector optics.
• Rinse out any solvents from the flow cell, for example, by using isopropanol. You can
flush the flow cell by using the optional syringe injection/flushing kit (part no.
6078.4200). During longer idle times, the flow cell should not be filled with pure water to
avoid the growth of algae. Add a suitable proportion of isopropyl alcohol, for example,
and plug the flow cell input and output using the plugs that were installed when the flow
cell was shipped (→ Fig. 19, page 54). Using different plugs and tightening them may
destroy the flow cell.
• When shipping the instrument, remove the flow cell and install the special cover to
protect the flow cell opening. The flow cell must be shipped in its original packaging.
• Ship the module only in the original shipping container and observe the packing
instructions. Shipping the unit in any other packaging automatically voids the warranty.
If the original shipping container is not available, appropriate shipping containers and
packing material can be ordered from Thermo Fisher Scientific sales organization for
Dionex HPLC products. The packing instructions are included in the "Installation and
Qualification Documents for Chromatography Instruments" binder and are also available
on request.
If you are running Chromeleon, you can set the detector and HPLC system into the standby
mode or automate system shutdown, as described in the sections below.
Standby Program
A standby program sets the HPLC system into standby mode. The application can be
reactivated very quickly afterward. The pump flow is automatically reduced at the end of the
program, and the temperature of all temperature-controlled system modules, for example, the
FLD flow cell heating, can be reduced or the temperature control turned off.
Shutdown Program
A shutdown program automates shutdown of the HPLC system. The pump flow is
automatically stopped at the end of the program. Certain system components and functions
are turned off (for example, detector lamps, temperature control of the column oven or FLD
flow cell heating).
