Product Overview
The PDA-100 Photodiode Array Detector is an optical detector capable of
measuring the absorbance spectrum from 190 nm to 800 nm. A deuterium lamp
optimizes the UV range (190 nm to 380 nm) and a tungsten lamp optimizes the
visible range (380 nm 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 runs that do not require spectral data and it conserves disk
space.
Key PDA-100 features include:
•
Deuterium and tungsten lamps ensure low baseline noise, high signal
intensity, and applications flexibility in the wavelength range from 190 nm to
800 nm.
•
A 1024-element photodiode array optimizes spectral resolution.
•
A built-in holmium oxide filter verifies wavelength calibration accuracy.
•
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 host computer running PeakNet
®
6 or
Chromeleon
®
software (Release 6.1 or later). The detector communicates with the
host computer via the Dionex DX-LAN
™
interface.
