1.1 Detector Overview
The Thermo Scientific Dionex
™
ICS Series Photodiode Array Detector (Dionex
PDA) (P/N 074114) is an optical chromatography detector capable of measuring
absorbance signals and absorbance spectra from 190 to 800 nm. The Dionex PDA
can be used with the following Thermo Scientific Dionex systems: the ICS-5000
(analytical systems only), ICS-2100, ICS-1600, ICS-1100, and ICS-900 (as well
as some legacy systems). The Dionex PDA can be used in numerous laboratory
environments for routine analysis, as well as for sophisticated research tasks.
A deuterium lamp optimizes the UV range (190 to 380 nm) and a tungsten lamp
optimizes the visible range (380 to 800 nm). When using the Dionex PDA, up to
five single wavelengths (2D chromatograms) can be collected without the
necessity for collecting 3D data. Collecting individual wavelengths instead of the
spectra offers two advantages: it eliminates the need to perform signal extractions
for analyses that do not require spectral data and it conserves disk space.
