B • Installation; Facilities Requirements - Thermo Scientific Dionex ICS Series Operator's Manual

B.1 Facilities Requirements
•
Make sure the Thermo Scientific Dionex ICS Series Variable Wavelength
Detector (Dionex VWD) installation site meets the power and environmental
specifications listed in
•
Optical detectors are sensitive to vibration. Provide a sturdy, vibration-free
workbench of a height that ensures convenient access to the interior of the
Dionex VWD.
•
Make sure the workbench surface is resistant to solvents.
•
Allow at least 6 cm (2.4 in) of clearance behind the Dionex VWD for power
connections and ventilation.
•
Optical detectors are sensitive to changes in temperature and light. Protect the
detector, column, and all tubing from drafts and direct sunlight. Do not
operate the detector unless the lamp housing cover and front cover are in
place.
•
For mobile phase generation, or when manually preparing mobile phase and
regenerant, use ASTM Type I (18 megohm-cm) filtered and deionized water
that meets the specifications listed in
