Product Overview
The Dionex PDA-100 Photodiode Array Detector (P/N 064532) is an optical
detector capable of measuring the absorbance spectrum from 190 to 800 nm. 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 PDA-100, up to five single wavelengths (2D chromatograms) can
be collected without being required to collect 3D data. Collecting individual
wavelengths instead of the spectra offers two advantages: it eliminates the need to
perform extractions for analyses that do not require spectral data and it conserves
disk space.
Key features of the PDA-100 include:
•
The deuterium and tungsten lamps ensure low baseline noise, high signal
intensity, and applications flexibility in the wavelength range from 190 to
800 nm.
•
The 1024-element photodiode array optimizes spectral resolution.
•
The built-in holmium oxide filter verifies wavelength calibration accuracy.
•
Five flow cells are available for standard, semi-micro, and semi-preparative
applications.
•
The front panel LEDs indicate detector status at a glance.
•
Four analog outputs support data collection on alternate data collection
systems.
The PDA-100 is controlled remotely by a computer running the Chromeleon®
Chromatography Management System. The detector communicates with the
computer through USB (Universal Serial Bus).
To take full advantage of the capabilities of the PDA-100, order Chromeleon with
the 3D Data Acquisition license. This license is required in order to perform:
•
3D data presentation and spectral analysis (real-time or post-run)
•
Peak purity analysis with selectable criteria
