VWD-3100 and VWD-3400RS Variable Wavelength Detectors

5.7 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 dummy flow cell) must be
installed. This is to prevent that dust particles cause damage to the detector optics.
• If you want to move or ship the detector, retighten the locks on the bottom of detector to
secure the optics during shipment (→ Fig. 8, page 34). Push the cardboard, which carries
the instructions for securing the optics, under the orange locks on the detector bottom as
shown in the picture, tighten the locks, and wrap the other end of the cardboard around
the font panel door.
• Rinse out any solvents from the flow cell, for example, using isopropanol. For direct
injections into a flow cell, the flushing and injection kit, including an appropriate syringe,
is available from Thermo Fisher Scientific (part no. 6078.4200).
• 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 following sections.
Standby Program
A standby program sets the HPLC system into standby mode. The application can be
reactivated very quickly afterward. The main program steps:
• The pump flow is automatically reduced at the end of the program.
• The temperature of all temperature-controlled modules in the system is reduced.
Shutdown Program
A shutdown program automates shutdown of the HPLC system. The main program steps are:
• 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).
