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

B.1 Facilities Requirements
•
Make sure the installation site for the Thermo Scientific Dionex ICS Series
Photodiode Array Detector (Dionex PDA) meets the power and
environmental specifications listed in
•
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
Contaminant
Ions–Resistivity
Organics–TOC
Iron/Transition Metals*
Pyrogens
Particulates > 0.2 µm
Colloids–Silica
Bacteria
* Iron/transition metal content not specified for ASTM Type
I water
Table B-1. ASTM Filtered, Type I Deionized Water Specifications
•
Optical detectors are sensitive to vibration. Provide a sturdy, vibration-free
workbench of a height that allows convenient access to the interior of the
Dionex PDA.
•
Allow at least 6 cm (2.4 in) behind the Dionex PDA for power connections
and ventilation. Do not block air flow to the detector. During operation,
room air must be inducted into the detector to cool the electronics and
dissipate the heat generated by the lamps.
