Drain Port and Drain Tube
Liquid (for example, from a leak) is routed from the drip tray inside the
detector to the drain port on the rear panel. Connect the drain tube
(P/N 055075), provided in the Dionex VWD Ship Kit (P/N 064787), to
the port. See
Place the free end of the drain tube into a waste container. To ensure
proper drainage, position the waste container below the level of the
detector.
The drain tube must remain below the drain port. If any part of the
drain tube is above the drain port, the drip tray may overflow inside
the detector.

Operating Guidelines
2.5.1
Wavelength Selection
There are two key criteria for determining the wavelength for an analysis:
•
Sample components should absorb strongly at the selected
wavelength. For best results, select a wavelength on the absorption
maximum. For a list of wavelengths for the absorption maxima of
various chromophores, see
•
The mobile phase should be "transparent," showing little or no
absorption at the selected wavelength.
2.5.2
Mobile Phases
Mobile phase quality significantly affects detection limits and instrument
performance. To ensure optimal performance of the detector, observe the
following guidelines:
•
Prepare all mobile phases and reagents with spectro-grade solvents,
reagent-grade chemicals, and ASTM Type I (18 megohm-cm)
filtered, deionized water that meets the specifications listed in
Table
•
Degas all mobile phases before use and maintain them in a degassed
state.
